Low Virtual Memory, lsass.exe Massive Memory Commit

[tamorli]

Hello, I've recently been experiencing random crashes to desktop while gaming (Dishonored 2 specifically). Looking through the Event Viewer, a Resource-Exhaustion-Detector warning is issued around the time of each crash.

It appears that lsass.exe is the culprit here, asking for a whopping 49 GB of virtual memory. When checking the pagefile (system managed) it is around 49 GB as well. I've spent some time searching for a solution but have found nothing substantial. It appears to be a memory leak of some sort but I am stumped on how to proceed with debugging. Any help is greatly appreciated, thank you.

EDIT: Using Process Explorer I identified NoMachine as a likely culprit, nxhost.bin was popping up repeatedly while the virtual memory commit was steadily rising. Since killing the process the commit has not increased, will update if the issue does not reappear.

From where did you download the game (Dishonored 2) itself from?

Though you seem to have stopped it for now, I have to ask if the lsass.exe file causing the problem is located in system32. If not it could be an infection. If it is, it sounds to me like you're had a borked security update.
