Detecting intros in daily analysis gets stuck on some files

I’ve been monitoring this about a week or two and the overnight analysis gets stuck on some files when Plex says it’s “detecting intros”.

I noticed a high load on my fileserver starting at 4 a.m. and ending at 6 a.m. every night, so I figured it had to do with Plex, as that is when the scheduled tasks take place.

I logged the locked files during that time of high load, and sometimes Plex gets stuck on a single video file for those two hours, and sometimes it doesn’t let go. The high load continues until I restart the Plex service.

It doesn’t seem to discriminate on a specific video filetype, and the file sizes are anything from 200 MB to under 1 GB, so two hours should be plenty of time to process the audio and detect intros.

I was wondering maybe if detecting intros gets stuck on a file, there would be a timeout on when it should close the file and move on. I’d prefer it if some intros fail in a way that it can move on with the analysis and doesn’t get stuck on a file causing a high load either.

I could collect some logs if needed, if I’m pointed in the right direction!

Looks like this thread might be related.

My issue is ongoing and Plex is unusable most days now (well beyond the scheduled task hours) until a restart of the Plex service so that intro detection is canceled.
