Hi there,
I’ve a very weird freezing issue when using Plex under Docker.
So my setup:
- Dedicated physical Docker Server (Minisforum MS01 - Core i9 - 96GB RAM)
- Almalinux 9.4 fully patched
- Plex 1.40.4.8679 (latest available that day, but previous has the same issue)
Some important infos:
- it is not a transcoding issue because several videos I have trouble with doesn’t require transcoding.
- the MS01 is connected with a LACP bond 2x10Gbps (The file share too)
- the bond is configure with a trunk, including several VLANs, one of these VLANs is dedicated to NFS share traffic
- NFS shares are mounted on host at boot so containers can have access to movies, music, etc…
- I noticed issues are coming randomly but apparently only on big files with higher quality
- The host is chilling, no CPU struggling and of course, not the network either
The problem itself:
- I will start watching a movie and randomly, movie will freeze
- during that time, other docker instances will be “cut” from network too
- after a few minutes, all applications are back to normal again adn I can restart the movie
- For testing purposes, I created a test instance of Jellyfin, the same issue occurs too, so I can’t blame Plex but server is recovering way faster with JF.
- Problem occurs on movies that I know had no issues before
Might be the host (NFS, etc…) or Docker itself but that’s why I don’t really know where to start and how to troubleshoot.
Any help would be very much appreciated!
Thanks in advance
