This has happened 3 times now since I updated PMS to version 1.9.6.4401 (beta channel, linux) about a week ago. I’m not sure what version I had previously but it was a couple months old.
For no apparent reason whatsoever, I hear my server fans spin up and go to check what’s going on and Plex is transcoding something, except nobody is watching anything. It’ll sit there and transcode for an hour or more with the CPU running full tilt.
In this case, I had just added 2 movies to my library, and scanned library files. Scanning finished, and the server started transcoding one of those two movies.
There was one more update for PMS, so just now I updated it to 1.9.7.4460. After about 1 minute of Plex starting back up, it started transcoding the other movie I added to my library.
I also do not have “optimized versions” enabled. I’ve had plex running on this same server for over 4 years and this has never happened
