Plex Crashes Randomly

Server Version#: 1.29.2.6364
Player Version#: 1.58.1.3380-ea159c52
OS: Ubuntu 18.04.6 LTS (Bionic Beaver)

Not sure how to reproduce this bug, but it seems like it may be crashing when generating new chapter thumbnails:

Generated new chapter thumbnails for Betrayals (1).
Generated new chapter thumbnails for Glass Houses.
Generated new chapter thumbnails for Parents Find Out.

The previous logs consistently stop after:

Generated new chapter thumbnails for Parents Find Out.

This leads me to believe that it is either hitting an issue generating the thumbnail for Parents Find Out or the next thumbnail that it attempts to generate.

After it crashes, I have to manually:

docker restart plex

After which, it will become accessible again and everything functions fine until the next time new chapters are generated.

  1. Is there a way to trigger the new chapter generation to confirm? I would like to see if I can reproduce the crash.
  2. Is there a way to clear the thumbnail cache? Maybe something in there is borked.

Happy to provide any and all logs needed to further debug.
