Hey all,
I noticed in around October 2022 - Nov 2022 that our primary polling server had a memory leak with the Local Subsystem Authority Service (LSASS.EXE) process.
The memory allocated to the server would slowly fill to capacity within a month and then require a restart of the polling server and I'm now seeing that the memory is being consumed even quicker, roughly within 2-3 weeks the memory is completely consumed and requires reboot. The issue appears to only impact my primary polling server and not my additional polling servers.
Primary poller has 48GB of memory allocated to the virtual machine with 20 Cores, running on Windows Server 2016. All updates are installed up until January 2023. The APE's we run are running Windows Server 2019.
Wondering if anyone else has seen this and thoughts on what it could relate to?
Below you can see the physical memory % usage on the primary poller, the dips indicating where the reboots took place:
