Thank-You

 

Large amount of Paged Pool memory usage over time


I have been fighting with this for some time and I can't figure out what it is. Over time, my Paged Pool memory usage keeps climbing until eventually I have to reboot to clear it out. It is a tough problem to search for because most people seem to have a problem with non-paged pool memory and all of those problems get included in the search results.

I have 32GB of RAM and once the paged pool reaches around 18GB or so it starts to bog down and get sluggish. And when I say 18GB, I mean 18GB with nothing open. I have my typical tray stuff, which I have tried killing, but nothing releases the RAM. I have let it climb all the way to 32GB before, but then the computer becomes useless and took about a half hour or so to shut down.

When I run Rammap it shows that paged pool is huge, and in the process list there is a process called MemCompression that has an extremely large amount of RAM in use. Not the full size of the paged pool, but definitely really big.

There are several threads talking about using Poolmon to track down processes using lots of paged or non-paged pool memory, but the process on mine that is extremely large has a tag of Se, which is tough to search for in the strings because virtually every file has Se in it somewhere.

Right now I just rebooted again, so the usage is back to "normal" (if you consider 11GB memory in use normal for just having Chrome open) and my paged pool is around 2GB or so. It will increase again by this evening, so I will get some screen grabs of the Rammap and the process list. Any other screens I can grab that might help?

 

Very high ram usage, unusually high non-paged pool use by tag Etwr

I have been running out of RAM as of late and have narrowed down that something is leaking in the non-paged pool. My non-paged pool is almost 4GB. In addition to that, the working set of my paged pool is another 4GB (in use by an extremely similar tag). This is after a total uptime of 4 hours. Before my last reboot, my Non-paged pool had grown to about 7.5GB and paged had grown to 15.7 GB.

I am running Windows 10.0.14986. The problem started after the last update. Given that it is an Insider Build, I'm not so much complaining as taking this opportunity to learn how to troubleshoot.

Here are screenshots from task manager, process explorer, and poolmon.

procexp.exe:





poolmon.exe:





So far I have not been able to find the string "Etwr" in C:\Windows\system32 (using findstr /s Etwr *.sys)

Looking online for the Etwr tag gives me:

I have no clue what to make of that, as my understanding is that that would imply that the issue is with the Event Tracer which is a logging/performance analysis tool.
