Question Local Security Authority Process intensive RAM consumption

[sende2]

Server operating system version

Windows 2019

Plesk version and microupdate number

18.0.67 #3

Hi,

I have a problem with my Windows Server 2019 with Plesk Panel installed.
I felt the need to write to the forum because I couldn't find a solution.
The "Local Security Authority Process" service starts to consume up to 90% of RAM within 36-40 hours and causes the server services to freeze.
When I restart the server, the problem goes away, but after 36-40 hours the same problem occurs again.
When I check the server logs, I don't see any specific error.
The server is running ESET Server Security and the operating system is updated monthly.

Do you have any suggestions or recommendations regarding this issue?

Thanks,

Hello @sende2,

I would say there were no reported cases with the same behavior. Thus, I would assume the issue can be caused by the bug that was discovered in earlier Windows Server 2019 releases:
Local security authority process consuming high memory - Microsoft Q&A
Do you have the latest updates installed?

In general, Plesk should not affect this behavior anyhow.
