High memory utilization for Page table

Hi,

We are running a Windows 2019 core edition with features on demand (on prem server). The server is actually a Azure Application Proxy Connector.

The configuration is a 4 vcpu w/ 16GB RAM

We had several connection issues today and after troubleshooting using perfmon / sysinternal tools that the high memory was caused by the Page Table that is close to 5GB.

The Free system page table entry is not a problem... over 10 000 000 free.

The system cache resident bytes is low... around 200MB

Any hints ?

Hi @cthivierge

Sounds like a there might be a memory leak, have you try poolmon, I've had success using in the past to finding memory leak issues.

Thanks, it was my other option but poolmon monitor pool paged and pool non paged and those values seems to be ok for me. And all the process together were using max 8-10gb of memory.

And after i saw the page table using 4gb, i was a bit confused...

We had to reboot the servers because there was too much issues but because it's not resolve, my guess is it may happen again...

Thanks
