Jellyfin Instability and Crashes

[Efficient_Good_5784]

Thanks for the response! The SIMKL Plugin seems to report an error when it's actually a warning, it's merely stating that a user is not logged in as only a small handful use SIMKL. I can however give disabling it a go though, to rule it out. I also have been speaking to SIMKL developers to see if they can see a cause with their plugin too.

This is a huge chunk of the warning in your log file:

Code:

[ERR] [90] Jellyfin.Plugin.Simkl.Services.PlaybackScrobbler: Can't scrobble: User "REDACTED_USER" not logged in (True)

Maybe it's a warning, but I bet it's causing slowdowns on your system due to the huge frequency it's spammed in the logs.
Doing a find-all on the logs, that exact line is shown 1668 times on the logs.

What server version where you on before upgrading to v10.9.7?

As for the episode naming, I see two types from the logs:
1. Home Fires (2015) - S01E05 - Episode 5 [redacted].mkv
2. DARLING in the FRANXX (2018 ) - S01E07 - 007 - Shooting Star Moratorium [redacted].mkv

Jellyfin should ignore everything in the square brackets.
I would suggest to try removing the year tag and the extra episode numbers. As in, only keep the "S##E##" format:
1. Home Fires S01E05 [redacted].mkv
2. DARLING in the FRANXX - S01E07 - Shooting Star Moratorium [redacted].mkv

I think the TMBD provider may not be able to pick up the metadata properly based on the naming of the episodes.
