Server Version#: Version 1.31.1.6716
For a while now my server has been pretty chaotic when it comes to detecting intros and credits. Its almost constantly doing it, and creates a CPU rollercoaster (as seen in screenshot).
While I appreciate this feature very much, I wonder if perhaps the state of my PMS is somehow corrupted. Is this a normal pattern? Is there a way to kind of optimize/reset the intro detection for my library? I’ve often noticed it re-processing the same episodes, etc.

Yes.
Set the time window for server maintenance to a time of day where you are not using your Plex server much. Set it to perform intro and credits detection not while ingesting new media.

The algorithms for intro/credit detection are sometimes updated in a new server version. All detections done with an earlier version are updated automatically.
Apart from that, make sure that your server’s general `/temp` folder has plenty of free storage available as it is used during detection. A lack of free space leads to the detection being aborted and retried next time.

@OttoKerner thanks for the reply.
I do have my scheduled tasks setup for an overnight window, however intro/credit detection does not seem to adhere to this window, and runs outside it. Are you 100% certain that intro/credits detection is considered ‘background maintenance’?
My tasks config is vanilla default:

That does seem to be what I want, but I don’t see a specific setting for that, can you elaborate?
Thanks.

You can find it under
Settings - ‘Show Advanced’ - Server - Library

Okay, thats helpful. It was indeed set to run upon new media. Let see if that addresses the issue.
