Plex Stalled Detecting Intros (Linux/Docker)

Server Version#: 1.112.0.359-0d79a49f
Player Version#: N/A

Hi All –

I decided to make a fresh post because the topics in this forum, which I could find, that covered my issue were all locked. However, I found a solution from a clue in the forums so I will record it here.

My Server: My plex media server is running in a docker container on a Linux based NAS. Not sure if this will apply across platforms.

Symptoms: When adding new content in TV Shows or, when scheduled task for TV Shows would run, the detect intro feature would stall on a season, and never make progress. It was not slow, and combing through logs did not reveal a problem with the actual source files, the source files analyzed and would play correctly.

Other Sources: This thread had the same issue ( Detecting Intros stuck forever - #7 by Tvfan567 ) and a Plex employee noted a problem in the log files, which ultimately provided me the idea for the solution.

Solution: This is the solution I found for my Docker implementation of Plex. Based on the thread above, I opened a console for the docker container itself. First, I set the permission on the tmp folder so it would ensure it had read/write access, then I browsed to the /tmp folder and found nested folders. I cleared the /tmp folder of all files and folders. Restarted the docker container and my issues were solved, all shows that were stuck detecting intros and failed to mark intros are now marked and the activity indicator is idle (not spinning all the time).

I hope this post will index such that people having this issue in a similar situation can find it, the solution is quite simple for this particular problem.
