Thanks for the log files.
Have you tried to move the PlexMediaServer shared folder to a non-default location (i.e. something different than /volume1/PlexMediaServer)?
You have what appears to be a Plex Data Folder (or copy thereof) in /volume1/Plex Movies/ which is being scanned by the Plex Movie scanner.
This is causing your system instability.
QUESTION: Does the NAS have a /PlexMediaServer shared folder?
QUESTION: If yes, does it have the “normal” Plex Data folder structure, with .../AppData/Plex Media Server containing subfolders for Cache, Codecs, Crash Reports, etc.
IF YES TO BOTH:
- Stop Plex Media Server.
- Using File Station, delete
/volume1/Plex Movies/tmp_transcoding.
- Using File Station, move
/volume1/Plex Movies/Library to a location not scanned by any Plex library.
- Start Plex Media Server.
After Plex Media Server starts, use it as normal and see if it is stable. If the problem continues, pull and post another set of server logs.
If Plex Media Server is stable, you can later delete the Library folder you relocated from Plex Movies.
NOTE: Also, verify the Transcoder Temporary Directory in Settings → Transcoder. Make sure it is not pointing to any location where media resides (/volume1/Plex Movies, /volume1/Plex TV, etc.).
