Serious memory leak in nonpaged pool (Irp tag)

Q: Serious memory leak in nonpaged pool (Irp tag)

I have a serious memory leak in nonpaged pool, which happen to be Irp packets. Here is the whole story.

The system is Win7 Ultimate x64 which I primarily use to host some VirtualBox VMs. Around beginning of May I noticed that the box started to lock up and it was rock solid for almost a year before then. I discovered that the reason for lock ups is a memory leak that east up its 16 GB of memory in a few days. I started digging deeper and figured out that the nonpaged memory grows from the typical 500 MB or so to a few GBs in a couple of days. The poolmon tool pointed to Irp tag as the clear offender.

I thought it could be some update or new driver that got installed, so I restored the system from an earlier image. I went back to images as far back as November, October and September last year, but nothing helped. The system was working fine till about end of April, so I was very surprised that reverting back to the time the system was working OK did not fix the problem.

Anyway, further troubleshooting with driver verifier (log file analysis) did not point to any driver with suspicious amount of allocated memory. So the next step was to force a memory dump with driver verifier running and use !verifier kernel debugger extension to see the memory allocated.

First of all, driver verifier puts a lot of load on the system, so it stops responding after few hours with CPUs pegged at 100%. Also, the system is much slower when driver verifier is running and the memory leak happens at the much slower rate.

I recently forced a memory dump after about 8 hours of system uptime. The nonpaged memory was about 915 MB, so I'd expected a clear indication of what driver has plenty of memory allocated. Unfortunately not so.

The !verifier 1 provided this output:

There are no Irp tags anymore with driver verifier active (well, with the options I've enabled), but Irpt and Irp+, however Irpt tags cannot be found in memory dump at all, but Irp+ tags have the majority of memory allocations anyway based of poolmon output.

So I'm at a loss right now. I've exhausted all the troubleshooting options I knew about and still I have no clue what is the damned thing that is leaking the memory. I had some wild thoughts that it could be something hardware related, but when I boot to an XP maintenance partition there is no memory leak whatsoever.

Are there any kernel/drivers gurus here that can help me fix the memory leak issue?

Preferred Solution: Serious memory leak in nonpaged pool (Irp tag)

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: Serious memory leak in nonpaged pool (Irp tag)

Memory leaks occur for only one reason, and that is flawed & poorly programmed software. You are running some 3rd party (non-Microsoft) software that is not releasing memory after it is done with it. It's the software's fault.

It might be patched in an update, but if not there is nothing you can do other than re-coding & fixing the software.

Hi there,

I'm experiencing some serious memory leaks. At start up the initial RAM usage is around 18%, after leaving it on for about 12hrs with only background programs, the ram usage just rose to over 80%%. Then it started to lag and freeze, the only way to get back to normal is restart. RAMMap shows that Nonpaged pool is using up all my RAM.

After following this guide here Pushing the Limits of Windows: Paged and Nonpaged Pool - Mark's Blog - Site Home - TechNet Blogs, I used poolmon.exe and strings to find out the culprit is FWPKCLNT.SYS

(these pics were taken after 3hrs ontime)

Any idea how to fix this problem? Any help would be most appreciated!!!

Apparently you need to tell Windows that you want to use the machine as a file server and that it should allocate resources accordingly.  Set the following registry key to ‘1′:

and set the following registry key to ‘3′:

Heyo all.
It's been three days that I've trying to solve this problem, and right now I have no idea what to do next.
I noticed that my memory usage would get very high as time went on. Windows would use 3GB by itself, with no processes accounting for this. This also caused a bluescreen at one point with a "Kernal inpage error". I've checked in process explorer and the All Users section of task manager, but the RAM usage amounts don't add to the total usage. All of this memory is in my Nonpaged pool, and after further searching I've found that it increases whenever a program is downloading something from the internet. I've updated my Ethernet port's drivers but that has had no effect whatsoever.
I've tried tdsskiller, combofix, and ran a scan with Avast and Malwarebytes. All of which have found no problems.
Any help would be greatly appreciated, it's annoying to have to reboot my PC every 2 hours if I have a download running...

A:Downloads increase nonpaged memory pool usage.

Open the Task Manager and look in Processes and watch to see if a specific process is increasing in its use of memory.

Hey guys,

I have no programs running, just chrome with a couple of websites. On my previous pc with windows 7 i've never had the memory use more than 5 GB just for chrome. Also, the paged pool seems to fill up the longer I use my pc. I've read numerous threads with people saying that it is normal for a pc to use all the RAM because otherwise it's useless RAM. But I don't really believe that something like this is normal. In most threads people talked about a memory leak in the non-paged pool.

I find it also very weird that when I look at my processes they just don't add up to the 5 GB in use. Using rammap or process explorer doesn't show annything at all.
Here are my specs:
Lenovo B5400
Windows 8.1 64-bit (6.3, Build 9600)
Intel Core i5-4200M CPU @ 2.50 GHz (4CPU's)
8192MB RAM

I'm having real problems with League of Legends, I just get too much lag when I play. I have a constant 40 ping so that's not the problem, my fps is 60-70 so that's not really bad. But I just get these random stutters every few seconds. Also when I browse my pc is just acting too slow for it's specs.
I hope someone can help with this problem as I am a noob when it comes to computers. I paid about 700 euros for this laptop and I find it sad that I this stupid problem. I've already disabled superfetch and I really don't want a link to another thread as I've read every single one of them and I'm getting nuts


A:Windows 8.1 - Memory leak problem in paged pool

Hello SebaaVH,

You appear to be one of those affected by this Google Chrome bug that only affects "some." Now, since I don't know if they ever fixed it (I don't use Chrome), I would suggest trying a different browser (i.e., Firefox or Opera) to see if that fixes your issue. Now, some have stated they fixed their issue by clearing their browser cache but that would be just a band-aid IMHO:

Massive memory leak, though memory usage does not show for GC in task manager:

Regarding your League of Legends issue, I don't play it myself but your issue (or something similar) has come up several times quite recently and, if you do a Google search for that issue, you will find tons of people having issues when playing it online. You might be better off seeking assistance at a gaming forum for that specific issue IMHO.

Good luck.

Just got on the computer now, and suddenly everything seems to be slow, I checked the memory and found out that some program is using 94% of the memory, when I was looking for the program I found out that no program is using that amount of memory, 200 at most.

I downloaded RAMmap to map out the memory, and found out that about 94% of the memory is Nonpaged Pool (unallocated?)
. Please see the image below:

As you can see the memory leak clearly.

Here is a second picture, after a computer restart, without firefox it gets to 15% although there is no application who is running on 15% (of 8G, is about 1,000MB of process, which in the picture you can see that it cant be). - maybe it's ok maybe not, in both cases there is a leak as you can see in the first post.

Hi I have a 8gb RAM laptop (and it isn't Samsung, I've seen this problem with that brand mainly) and recently the RAM usage has been far high than it normally ever is (over twice). I used the poolmon executive to find out what it is and the tag ECMC is using
2.15gb of nonpage pool space. I tried to do a findstr /s search to see what this driver was but when I did it with a normal command prompt it found nothing. Even weirder, when I tried searching it under an admin command prompt it return this string of gibberish,
twice (this isn't spam I swear):

I'm running XP SP2, and experiencing a non-paged pool leak of about 150 MBs a day. The pool will fill up after about 42 hours leading to a BSOD (0x000000f4). Poolmon is indicating the tag IRP is allocating ~20 bytes constantly and never freeing it. It's probably a driver, but I can't get any closer than that to finding out which one. I also monitored the leak in safe mode with no networking and it still leaks there. Could anyone perhaps help narrow it down more?

Like the tittle states is it possible for a browser or browser extension to cause memory leak in the non page-pool.

A couple of of day ago I switch over to Opera and had memory leak in the non page-pool that paralyzed the machine till I rebooted.

Asking cause a few days prior I was messing around with a few of my drivers and I have a new motherboard coming and was thinking of just popping the hard drive on without doing a fresh install of windows, since I have an upgrade version of Windows 8.

A:Browser cause non page-pool leak

What are you using to show that there is a non-page pool leak? Is this showing in events under administrator tools? Really need more information.

Hey guys,
I've learned quite a bit from these forums now by lurking and finally got my debugging tools working right with the symbols and all.
Anyways, I wanted some second opinions on these dumps.
Here's info on the system:

-x64 Embedded (App compatibility template) ?
- 3 weeks old, unused hardware, fresh install.
Im guessing it's memory and not driver related because I get these errors:

Invalid system memory was referenced. This cannot be protected by try-except,
it must be protected by a Probe. Typically the address is just plain bad or it
is pointing at freed memory.
Could not read faulting driver name

The pool is already corrupt at the time of the current request.
This may or may not be due to the caller.
The internal pool links must be walked to figure out a possible cause of
the problem, and then special pool applied to the suspect tags or the driver
verifier to a suspect driver.
Seems like both of those are related to memory.
I've also got some memory corruption errors too.

Thanks in advance for any input on these. Curious if i'm on the right track.

Hello, I'm running a 64 bit Windows 10 laptop. On idle, the System process is showing a high memory usage of more than 150 MB, usually more than 200 MB. Using poolmon the pooltag SpDN showed up with a memory leak. It leads to the Intel Matrix Storage Manager driver, iaStorV.sys. How should I go about fixing the problem?

A:High memory usage / Memory leak caused by Intel driver


Since this is a Intel driver I doubt the WDK can fix it.
You may try to see if there's a more current version of Intel's RST available for download and see if that fixes the leakage issue.

I am helping my parents troubleshoot their computers.  My feeling is that they are both infected with the same virus/trojan but I can find it or figure out what is going on.  
The each have identical laptops and both are experience identical problems.  Both are running Avast! and both systems are not turning up any discovered viruses or trojans during scans.  I am on the verge of completely refronting both of their laptops and am really hoping I can avoid having to do that.  I suspected that maybe they were both infected with "poweliks" but the below FRST shows (at least I think so) that neither are infected with that trojan.  I am now thinking its a memory leak on some recent driver/app update - but either trojan or memory leak, I am not finding it.
After a clean reboot, within 24 to 48 hours both systems begin to get very sluggish, both audio and video starts to skip and lag, both mice bounce around like crazy when trying to move the pointer.  After about 72 hours the laptops simply freeze to the point that they have to pull the batteries to get them to shut off.

To start, I have Windows 7, on Sony Vaio laptop.

I have been working on the issues with the malware removal team, but now machine looks clean, I am still having issues.

When starting the computer and going to the task manager, I can watch explorer.exe start at about 18K memory usage and then grow constantly until it is running with almost all of the computer's physical memory after about seven min. I cannot get the context menu to show up after a few min by right clicking on anything.

I had been experiencing "freezing" while playing Eden Eternal (an online role playing game) before that, which made me consider malware and seek help here at BleepingComputer. The freezing has ended, last time I played on that machine at least, but now there seems to be some issue with the explorer.exe taking all of the memory. I haven't been using the machine since I don't trust that there's not something running in the background that shouldn't be.

In resource monitor there were "connections" that had "-" for both the name and the PID, but I don't know if that was the malware of if that's normal somehow?

Issue with explorer.exe seems to be limited to only one user account, and not the other one. That is to say that if I log on one of the other accounts explorer.exe behaves normally, as far as memory usage.

So I've had this problem for a few months with my thinkpad x220, win7 home premium 64 bit. I used ccleaner, run memtest86 multiple times, chkdsk multiple times, sfc scan multiple times, none that helped. Sfc always detects errors but always cannot fix some of them. I have mse, avast, and malwarebytes and scanned them with absolutely no results. I've run rootkit scanners with no results.

Basically after a few hours the memory use rises up to ~95% out of my 8gb, with absolutely no intensive processes running. I'll attach rammap and processexplorer screenshots. I know this is not "normal" behavior because once my ram goes over 85% the system slows down to where I can't end tasks, open new programs, even things like deleting a file take minutes. Once it reaches 90 or 95, my screen starts flashing black(kind of like if you blink fast). I have to hard restart every time this happens. This is not normal, I've had "experts" on other forums tell me its win7 using the ram to its greatest. Its not, As soon as I restart and open my usual programs(browser, steam, openoffice, winamp, utorrent) my ram is at around 30 or 40 percent. If I leave the same programs open, and just leave it on for ~4 hours the ram gets to 90% and my screen starts flashing and I have to reboot.

If you look at the rammap and process explorer shots, the most ram intensive programs are chrome and firefox, but they only use ~500mb each. Everything else is only 50-100mb and do not add up to the 7... Read more

If you get the builtin Uninstaller for the app use that and once you're done click Finish
Back inside RevoUninstaller click on Next
Let RevoUninstaller scan for left over registry keys . Click on Select All and choose Delete .
Once done click on Next.
Let the left over files and folders be locates then Click on Select All then click Delete then Next and you should be done .

Hello all. New member here. I have had an issue with my PC since I "upgraded" to windows 8.1 earlier this year that is driving me batty. Unfortunately, I upgraded the hardware (motherboard, CPU, and RAM) at the same time, so I can't rule out a hardware issue completely. The issue stuck around despite a total hard disk wipe and reinstall from scratch.

I'm a relative noob as far as this sort of troubleshooting, and I'm really not sure how to proceed. My normal modus operandi has been to simply wipe and start over if I ran into serious enough issues, but that did not work this time. Months of google searches have not really yielded any progress, so I thought it could not hurt to ask here.

So the problem. Basically, the longer the system runs, the more memory it uses. Eventually it freezes up, and itf you let it alone long enough after this starts, it will finally reboot itself. Doing anything intensive hastens the process of memory drain, basically the harder it works, the faster it happens. If I am using the PC hard, it only takes a couple hours to burn through all 1 GB. If I am away for days with nothing but background processes running, it takes a few days, but it eventually crashes and reboots.

The only thing that might be slightly out of the ordinary for most users is the fact that I use the PC as my TV and DVR through Windows Media Center and the use of a Silicondust HD Homerun Prime cablecard tuner. Other than that, it's pretty basic stuff on my... Read more

Has anyone else noticed that chkdsk uses all available physical memory (if you let it run long enough)?

I find that if I run chkdsk and watch the memory usage in task manager it jumps by about 50MB every 2 seconds or so until it either finishes or hits around 3.2GB at which point my physical memory shows 99% used (I'm running 4GB), and the system of course slows to a crawl.

If you just run a quick chkdsk on your boot drive you may not notice it, but try running something longer like chkdsk /r on a flash drive or chkdsk /f on a bigger internal drive (but not your OS drive as this would require a reboot) and watch the memory usage climb. I have duplicated this on both systems I have running win7. My XP machine (checking the same USB flash drive) uses a much more normal amount of memory for chkdsk (20 - 30 MB).

Anyway, just looking for suggestions, as I have 5 old hard drives that I would like to check. Normally I would run all 5 at once, but with this system it's just not possible as they each use about 700MB of memory and once all the system RAM is used up the disk checking process slows down a lot.

A:chkdsk high memory usage / memory leak

chkdsk /r is implys /f if you only doing NTFS format then try /I or /D or /C

/I NTFS only: Performs a less vigorous check of index entries.
/C NTFS only: Skips checking of cycles within the folder
/B NTFS only: Re-evaluates bad clusters on the volume
(implies /R)

Now i'm using windows 10 but I had this problem also when using windows 8.1pro.
The windows 81.pro I have the original dvd here and I tried few times to make clean install.
Also windows 10 I got it free online and the same problem.

For example now i'm using Edge I have two windows opened in one I have 10 tabs open and in the other I have like 20 tabs open. But the problem happen also with two windows and 6 tabs open in each one.

The problem is that once I start Edge or Chrome on windows 81.pro or windows 10 I see in Task Manager that the memory usage is about 60%. Then after some times without doing anything special the memory usage raise to 80-85% then ine many cases also to 96-97-98%.

Now and in most of the times I have in the background a game running in this case battlefield bad company 2 that take about 600-800MB of memory.
But it happen even if I close the game.

The only way to push the memory usage down is in the task manager to shut down the Edge/Chrome and all it's tabs.
Then to start the browser again.
I tested my pc with memtest I don't have any memory errors.
I don't have any blue screens. Can't figure out where is the problem.
My brother have like 10-15 years old pc then my one with 4GB ram and he can open like 20 tabs of chrome without a problem.

While the memory usage raise to 85-98% everything is running slow all the pc is slow almost freezing.

It also depends, what kind of and how many extensions you have.
Some of them might be causing it, try to temporarily disable all.
Finding a cause can be difficult, you can try CleanMem Free.

I am having a problem with my memory getting tied up / used up and not being able to access it again until I reboot.
Machine: Dell xps studio 8100
OS: Win 7,
Processor: i7 2.8
RAM: 16GB (max it will take)
Video: ATI Radeon 5700 (running 3 monitors)
Versions: As far as I know I am running current versions of everything, including video drivers, flash, chrome, etc. (I've tried running Chrome with both the build in version of flash and the system version -haven't seen a difference)
Browser: I nearly exclusively run Chrome / Canary with auto-updates so am at the latest builds.What seems to cause me to use up / run out of memory is after I play videos (YouTube, Netflix, etc.), the memory seems to get used, but is not returned to the system, even if the browser is closed and re-opened.

Right now for example things are working fine; I rebooted my system a couple hours ago (but have not played any videos). I have Adobe Lightroom running, Picasa, Chrome and Canary (currently 4 web browser windows open with 52 tabs open). Task Manager currently shows me using 8.20GB of ram, that seems pretty reasonable to me.

Normally my system will keep running properly (if a program is closed, memory is freed up) right up until I start to play any videos (YouTube, Netflix, etc.) then it will start using up more memory. (Of course I expect it to use more memory during playback) However, even if I restart the browser, the memory does not get freed back up. For example, jus... Read more

It didn't usually do this, but probably after some windows update it started happening. 50+% of 8gb ram used when idle. Task manager and resource monitor doesn't show what is using the memory. When I add up all the services, it doesn't even add up to 50%. More like 15-20% of total ram.
Does anyone have a fix? I've looked and already tried disabling the ndu.sys via the regedit (changing value of start to 4). It didn't work.
If you don't have a fix, perhaps you can guide me in trying to identify the problem.

Memory Usage Goes Up Gradually (Memory Leak)

When I starting the Windows (in the first few hours) everything is normal But after 1 day or 2 (sooner or later) the amount of available memory gradually goes down and the physical memory usage increasing. This increasing, continues until the memory usage reaches near the 88% and at that point , there isn't any memory available to operate any software . Also when memory reaches that point, I can't access any drive in the HDD; because everytime I want to open any folder, the following error appears :

c:\ is not accessible.
Insufficient system resources exist to complete the requested service

At this point, I even can't shutdown or restart Windows normally; I must restart windows manually by pressing the restart button. after restart, everything goes to normal again; but this problem appears again and again ... (I had to restart Windows every 1 or 2 days)

here is the screenshots of processes and performance tabs in the Task Manager (at 88% memory usage)

A:Memory Usage Goes Up Gradually (Memory Leak)

Hi, in cases like this I like to look to the most obvious cause and one very often ignored. One of the major problems in Vista XP and 7 is a corrupt pagefile . Can return all sorts of problems and is simple to fix and perfectly safe. Is the paging file on the C drive? Or have you moved it somewhere else, if on the same drive as the OS then:-

Go to control panel, system and security system
Click on advanced tab
In the performance section click on settings
Again click on Advanced

Select the Virtual memory custom tab and set max and min to 00, 00 click on set then apply and ok out. Reboot computer.

Now go back to VM settings and select "system managed size" again press set and apply and ok out Reboot to take effect.

This has created a new pagefile and set the VM to the preferred settings.

Let us know how you get on.

Hi, a friend of mine sent me here to figure out what I could.

I'm on a Sager NP5793 with Core 2 Duo 2.5ghz, 4gb RAM, a 512mb nVidia 9800M GTS, 320gb 7200rpm hard drive, and Vista Ultimate 64-Bit installed. It sits on a Notepal Infinite (small for a 17" widescreen, but the vents line up nicely) and I use a Logitech Cordless Mini Optical.

I got this laptop less than a week ago, and the first thing I did after installing XP SP3 32-Bit and Vista 64-Bit was install all the drivers from the bundled CD from Sager.

I've been noticing an average of 33% memory usage consistently, even when nothing is on. I thought it may have had something to do with the Aero theme, which shouldn't have had a problem considering my laptop's specs, but I disabled them to test, and my memory usage fell a whopping 2%.

I have 6Gb of DDR3 RAM and windows task manager tells me that 5.53gb of that is in use. When I add up the amount of memory that each process is consuming, it doesn't even reach half of a gigabyte. What is using my memory and how can I stop it?

A:Memory Leak?

How many processes are shown as running? Do you use any Torrent programs or peer-to-peer software? Also, open up your MSCONFIG file and see what is running from start-up. (START>ACCESSORIES>RUN....type "msconfig") Check the STARTUP tab. Post a screen shot of your startup selections if you like. Many processes are not needed at startup and you may just have a memory hog running in the background.

I am running Win7 x64, release version from MSDN. If I leave my machine on for 8+ hours, when I log back in it is using 5GB of memory. I have 6GB installed.

I have confirmed no spyware or viruses. I checked processes using Task Manager and Processes Explorer and nothing is using over 150MB and total was just less than 2GB when adding them all up.

It isn't making a whole lot of sense. What could be using RAM but not reporting its usage other then the OS?

Just in case it matters the machine is a 2008 Mac Pro, dual Xeon, 6GB RAM. Antivirus is AVG (which I have removed while I am not using the machine to see if that is the memory hog).

A:memory leak

As discussed previously, it sounds like a resource leak, but the real questions are "what's leaking?" and "can it be worked around without (re)coding the component in question?". This is all assuming you're already on the latest version of all the components involved, which tends to have a way of resolving (embarrassing) known resource leaks

The best way to troubleshoot is to start a Perfmon log straight after a reboot, and to keep it running until the "freeze" symptom manifests itself. Given it can take days, the trick is to keep the log file from growing to a monstrous size. That's done by being selective about what's being monitored, and how often perfmon records a "sample".

As a suggestion, create a Perfmon counter log to record all instances of all counters under the following objects:


Set the sample interval to say 2 minutes, and kick off the log soon after the next scheduled reboot. Stop the perfmon log only once you're confident that the machine is clearly being all weird in the particular way which you wish to analyse.

If you need more info on how to create the perfmon log, just yell. Ditto if you'd like assistance in analysing it. There's nothing particularly personal in there other than the hostname of your server and the names of the processes running on it.

Hi everyone,

Just recently, I've been having major problems with memory usage. Right when I reboot, all processes in my taskmanager are at normal, with the majority of programs running at 5-6 megs. But as I run a few programs, the memory usage of the majority of processes suddenly jump up to 30-40 megs.

For example, foobar2000, which usually takes 5 megs, now takes 44 megs. But if I close it and restart the program, it's back the normal 4-5 meg level, but it gradually consumes more and more memory.

Could this be the result of a virus? I ran Symantec and Spysweeper and came up with nothing (and even these scans are running at much lower speeds than normal).

CPU usage is also normal, just a memory problem.

Thanks in advance for any help.

Hi, recently I've noticed my comp has been having issues with slowing down a lot after being on for a day, I decided to start looking into the processes yesterday and noticed 1 svchost.exe process using 1.7gb of ram, about 8 hours later it was using 2.6gb of ram. After rebooting the readings went down to a more normal looking level with the physical memory use while a couple of programs are running being about 50% (my system has 4gb of ram)
I have been keeping task manager open and watching the memory usage, most of the svc processes increase slowly with occasional small dips but the increase is very slow, there is however 1 process that is increasing by about 1mb every 3-5 minutes. This process is the one involving network programs (winhttpautoproxy, wdiservicehost, nsi, netprofm, fontcache and fdphost)
I hear all these processes are linked to server 2008 which i didn't think was installed and thought wasn't needed on a standard home computer.
I double checked and ran a malware scan and a virus scan which both came back clear, so i have no idea what is causing such a rapid memory drain.

Exit FireFox before you leave and then re-open it when you get home. FireFox can remember your open tabs if needed.

I was just downloading somes big files with jdownloader while watching a movie, but the system was slowy getting laggy, so I checked the memory usage and i was almost full (90% of physical memory in use) and perfmon could not show me anything.

Right now, about ten minutes later, the memory usage is still the same, I killed jdownloader, java and kmplayer , but it still the same. I cant find who is guilty. I post some screens.

My cfg :

Core2Duo E8400 3GHZ
4GB DDR2 PC6400
Win 7 x64 Ultimate
Notes : I use nod32 AV (not smart security). Superfetch is off.
