    Non-Paged Pool Memory leak by enrolling VMware Workspace ONE


    Hi,

    I will explain you our problem.

    By installing and enrolling our Win10 machines Home/Pro/LTSC in Workspace ONE from VMware, it shows us a memory leak, so the non-paged pool of memory is increasing slowly until no memory will be available, and windows will freeze completely.

    This behavior is shown an fresh installed Win10 all editions with latest updates and drivers.

    I had one test Laptop which was on for 24 hours, no memory leak was shown. Then installed intelligent Hub to enroll our device in our MDM. After that the memory of non-paged pool was increasing very slowly, but was full at the the end of 48 hours uptime.
    I found that netio.sys is doing this by using most of the non-paged pool without releasing it. There are different hardware types showing all the same behavior.


    VMware say to me, that is not a bug of them, but Microsoft has to check first our machine to confirm that this is not a bug by Microsoft.

    What can we do?


    Best regards.

    :)

    is this memory leak?

    Hello RASHMIRANJAN1,

    I'm an independent advisor and hope this would address your questions.

    This is not a memory leak. A memory leak happens when a process or program failed to discard utilized memory when it is no longer in use. In that case, you would see a process or program consuming more and more memory over time.

    I wouldn't be worried about the paged and non-paged pools as they aren't excessively large in size. The paged pool is used to store handles of kernel objects, so it is normal to have some usage there. And non-paged pool is used by kernel and drivers of the
    operating system, so it is also normal for some usage there.

  3. High paged pool memory after leaving system on for quite sometime

    Oh, I see! Thanks for the clarity!

    Pageable memory controlled by memory management...that makes ALOT of sense! Oh well, at least the page pool stops at 1.2gb memory so I still have plenty of ram leftover for multi-tasking purposes. For virtual memory, I left it at system managed on C:/ drive. Otherwise, I'll try to update the network drivers and nvidia drivers. I know Killer Network drivers are highly proneable for memory leaks.

    Say, did Intel made an update of Intel Rapid Storage drivers for 4th Gen processors?

    Non-Paged Pool Memory leak by enrolling VMware Workspace ONE

    High paged pool memory after leaving system on for quite sometime

    1.2 GB Paged pool does not seem unreasonable for a system with 32 GB RAM. This value is higher for systems with large RAM sizes. In any event it is hardly likely to be the cause of your problem.

    The paged and non paged memory pools are used by kernel level components such as drivers and the kernel itself. The paged pool can be paged out at the memory managers discretion while the non paged pool must remain in RAM at all times. Task Manager will not tell you how much of the paged pool is in RAM.

    Memory usage in any modern OS is controlled by the system memory manager, always with the goal of maximizing overall system performance. When available memory is plentiful, as is shown in the screenshots, the memory manager will allow processes and other Windows components to use pretty much whatever memory they want without restrictions. But if there is memory pressure it is fully capable of reducing the paged pool usage to a small fraction of it's current value. But it will only do this if needed. Doing it at any other time would serve no useful purpose and would likely impair performance. Note that this is the RAM resident portion of the paged pool, not what is shown in Task Manager which would be unaffected.

    High memory usage, even if it is seriously abnormal, will not impair performance unless it causes a shortage. I have seen many Internet articles that get this wrong. It is not unusual for the paged pool to grow over time. Unless there is a memory leak, and there is nothing to suggest that here, this growth will stop.
