Problem with CPU at 100% and RAM does not stop increasing

[TheDreadPirate]

Looking over your logs, the only problem I see are the errors about tracking playback progress. But that doesn't seem to prevent users from watching videos, as far as I can tell. Other than that, the high CPU usage is from remuxing and audio transcoding for the huge number of users you have.

You have 20 cores and 40 threads, but they're pretty old Intel cores. You've disabled video transcoding, so that isn't an issue. You've limited the number of library scan threads now. The issue is just the number of users you have.
