Issue/Introduction
Running DX NetOps version 22.2.9
All users are getting logged out of the NetOps Portal at the same time roughly once per day. We upgraded to 22.2.9 in late June but didn't experience this problem until last week. We never had this happen on earlier versions.
When it happens all users get logged out at the same time. All 4 caperfcenter services are still running and the Portal server has not rebooted.

The following is seen for the console service when users are logged out but the command line shows the service still running.
STATUS | wrapper | 2023/08/31 08:22:20 | JVM appears hung: Timed out waiting for signal from JVM. Restarting JVM.

We also see this in the console service log leading up to these events.

Environment
All supported DX NetOps Performance Management releases
Cause
Console service is being starved for memory, running out and restarting, due to insufficient memory allocation during times of high load.
Resolution
This servers memory availability allowed for a 10 GB increase to the PC console services memory allocation which resolved the issue.
Additional Information
The Modify Maximum Memory Usage for NetOps Portal documentation topic covers the steps for changing memory allocation on Portal web server services.
