Hello @Rockstar7,

If you selected the hostname dimension I would understand is a single node, right?

If also detailing the time period, do you see the day that it was?

if so, did you also so Warnings on the Engine logs due to high memory.

Last but not least, could it be it was using virtual memory and hence it when up the 64GB mentioned on the Task Manager of Windows.

Cheers,

Albert

Hello @Rockstar7,

I would be very interesting to check the Engine logs of such day at such time and see if we see any warning on the virtual memory or not.

Cheers,
Albert

@Albert_Candelario on your suggestion, checked the logs, found the below warning. it happened again in recent times. attaching the logs for your reference.

WorkingSet: Possible cache depletion detected. Depletion factor=1.0,

We also see that indeed your virtual ram went really high:

WorkingSet: Virtual Memory is growing CRITICALLY beyond parameters - 82.351(44.799) GB

Potentially even higher as there are some lines missing on the log as we jump from line 13660 to 13790.

What is the concern on that warning, the one below:

WorkingSet: Possible cache depletion detected. Depletion factor=1.0,

I would suggest to open a separate post for that as might help other Community users too if looking for such information, let me know once done.

Cheers,

Albert
