Thanks for the logs.
There is a possibility that this is happening because of running out of tcp port numbers from the dynamic tcp pool - as mentioned in this forum post SOLUTION: Conversion failed. The transcoder exited due to an error - but all previous cases I looked at were on windows
The errors arose after scanning the TV and Movies libraries - these scans used started at 21:20:18 and the errors started at 21:20:46
We need to establish if the errors are to do with the tcp ports
The issue I linked to is being addressed as follows:
- update to curl used by Plex Media Server that will reduce the number of ports used by 66%
- Advice to users to reduce Timewait system setting for tcp requests and to increase the dynamic tcp port if there are large libraries
- Upgrade movies libraries to the new in-line Plex Media Server scanner that avoids use of the dynamic pool for scanning movies libraries
- For TV libraries, work is in progress to change the scanner to be in-line and there is already a forum preview release for this development work
I would suggest that on getting this failure, you find out what tcp connections are in place (using lsof and saving output to a text file) and what the dynamic tcp port range is and what the timewait is before ports are released - this together with the server logs will help establish if it is the same issue
