Server 2019 Resource Exhaustion problems

Anthony DePinto 1 Reputation point

Running into a problem with WIndows Server 2019 and Resource Exhaustion issues for low memory. Basically we run an application that historically we've been able to run on a VM with 3-4CPU 12/16GB RAM on Windows Server 2012 R2 with over 200 sites. Memory usage will be high, but we do NOT hit these low memory issues on the older version of Windows Server. On 2 separate instances of Server 2019, running 3CPU 12-16GB RAM and only around 40 sites it's at least once a day. Anybody have any ideas on things to look at as to why 2019 is handling things differently than 2012 R2? All sites are running the same software more or less.

    Firstly, I suggest that we could check for update to install latest security updates. This will update system OS build and system file. There may be different states for different system versions and software versions. So we‘d better make sure that the system and the software are up to date and compatible with each other.
    Then some settings below could be checked. Because the issue may be related to page file.
    You can modify PagedPollSize value at regedit to increase the size or PoolUsageMaximun to set a lower % were the memory manager start the trimming process earlier.

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Memory Management.

    PoolUsageMaximum (REG_DWORD) : value at which the Memory Manager starts trimming the pool. Default is 80, but you can set it to 60 or even 40.

    PagedPoolSize (REG_DWORD) : setting the value to 0xFFFFFFFF allocates the maximum paged pool.

    Also, you can uncheck "Automatically manage paging file size for all drivers" at virtual memory options and increase page file size.
    Hope this helps and please help to accept as Answer if the response is useful.
    Best Regards,
