3. You can see how the RAM will be occupied in big steps.

Happen since beginning of March 2023 I don’t know the exact Server Version, sorry.
Can you give some help to avoid this crash?

Same behavior with PLEX-Server Version 1.31.2.6810. :pensive:
No improvement noticeable in comparision to the earlier version.

Any idea, what can I do to fix the problem?
