Windows 10: Non Paged pool usage is extremely high

My non paged usage is extremely high, my pc has 16gb of RAM, my user is taking 1GB and the non Paged pool is about 12GB Any idea? on how to fix this.

:)

 

Extremely High RAM utilization, high Paged Pool

The issue started in mid-February when I received multiple warnings and critical alerts from my RMM software for several PCs I administer - the RMMs settings for RAM alerts are a warning at 85% and critical at 90%.
All of these systems have been deployed for over 2 years and I've never had any of them give high memory alerts before. Now, of the 12 PCs in the office, 10 PCs are going to critical alert with the RAM use slowly creeping up over a 4+ day period. The users are complaining of the PCs becoming slow, lagging, or unresponsive. A reboot tends to make the PC usable again until the RAM gets critical again.


Image 1 is RMM metrics from a users PC showing RAM (purple line) before the issues started, and after February 12th, the RAM creeping to +90% after the issues started
Image 2 is a current image of the RMM metrics for the last month









To make the issue more obvious, here is an image from our conference room Intel NUC, that is idle most of the time. I know that the spikes are the right side are while the PC was mostly idle and I was rebooting the PC to get the RAM to drop:




To help you understand some of the things I have tried, here are samples of the alerts I got from my RMM software:











As I mentioned above, I have 10 PCs, some are idle, having this issue. I have 2 actively used PCs that are NOT having the issue. In trying to troubleshoot, I have basically compared the idle systems with the issue to the 2 active user PCs that are not having the issue.
Here are images from Process Explorer, Task Manager and RAMMAP from an idle system that is having the issue:










Initially seeing epsecurityservice at the top of Process Explorer and in the RMM alert, I thought BitDefender Endpoint Security (GravityZone) was the issue. I applied a “disable” policy to BitDefender on an idle system and the issue did seem to stop after a reboot.

HOWEVER, seeing svchost in the list, I also tried a Clean Boot, but disabled everything EXCEPT BitDefender and my RMM software so I could continue to connect to the system.

Again, the issue seemed to stop with a Clean Boot and BitDefender still enabled.

So I compared Process Explorer metrics for a system with the issue and one that doesn’t have the issue and found that epsecurityservice.exe had roughly the same RAM use between the two systems… and the numbers were not increasing steadily over time.
This made me think BitDefender isn’t the issue but perhaps something it uses in the OS.

So I then looked at RAMMAP and Task Manager, and that is when I saw the extremely high Paged Pool on the idle system and a relatively small Paged Pool on the system in use. So I checked all the systems with the issue and they all have extremely high paged pools, even on systems that have been rebooted and left idle for days.

Here are screenshots of for one of my systems that is not having the RAM issue:










And just for a comparison reference, here is what my RMM metrics for RAM look like on one of my PCs that doesn't have the issue:





Here is a quick rundown of these systems configurations which is making it hard to determine if it is a driver issue since 4 different configurations are having the issue:





I'm not sure whether the huge Page Pool is okay, but it doesn't seem normal when compared to how my RAM utilization is for the 2 systems that are not having any issues.

If anyone has suggestions on what else I should try to resolve this, I’d greatly appreciate it.

If you want more information, please give me step-by-step simply to save time – I don’t want to waste any time assuming I know what you want and giving you the wrong info.

Thanks in advance for the help!!

 

Non paged-pool is too high

Hi Žiga,

My name is Umar. I'm an Independent Advisor, and I will be happy to help you today.

The high non-paged pool usage on your PC is likely causing the performance issues you are experiencing. The non-paged pool is a region of memory that is used to store critical system data that cannot be paged out to disk. When this pool becomes too large, it can consume a significant amount of your system's RAM, leading to performance degradation.

To address the high non-paged pool usage, you can try the following steps:

Outdated or faulty drivers can cause memory leaks in the non-paged pool. Ensure all drivers, especially for network and graphics devices, are up to date. You can do this through the Device Manager or by visiting the manufacturer's website.

Malware can cause high memory usage. Perform a full system scan with Windows Defender or a trusted third-party antivirus program.

Use Task Manager or MSConfig to disable unnecessary programs that start with Windows, as some of these might be consuming non-paged pool memory.

Corrupt system files can cause memory issues. Use the System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM) to repair system files.

Note: Ensure your Windows OS is up to date with the latest patches and updates, as these often contain fixes for memory leaks and other performance issues.

I hope this information is helpful. Please let me know if you have any other questions.

Best Regards,

Salfi Umar
