Background transcoder operation filling up disk space

Plex Media Server
1

Server Version#: 1.19.4.2902

Plex is creating a huge (34+GB) runaway temporary file that is filling up my OS drive and crashing everything. I find the temporary file referenced in the log in reference to some background transcoding operations, sample below. These are part of some automated operation and not a file anyone is trying to view.

There is a bug which causes the transcoder (while trying to identify tv episodes’ intros) to use the general system temp folder, instead of its explicitly designated location.
Settings - Server - Library - “Generate intro video markers”
Set this to “never” until the issue is fixed.

This should be the case in one of the next server beta releases.

Could you inspect the log a bit further, to try and determine which tv show and episode caused this outrageous file size?
