Unraid "crashing" randomly, requires full unraid reboot to restore

  • Server Version#: 1.43.1.10611
  • Player Version#: 4.159.0
  • Unraid: 7.2.5 issues was also happening on 7.2.4
  • Plex Docker: Linuxserver
  • Passing intel 13500t iGPU for Transcoding
  • Unraid Server Specs:
  • 13500t
  • 32gb DDR5 5600mhz
  • Plex is on 2x 2TB Lexar NM790 SSD’s (using /mnt/cache mapping)
  • using an LSI card in IT mode (note sure of the model)

I have been having a very strange issue the last month on my Unraid plex server, where I will loose access and plex will say no content available.
I will then check Plex and have SQlite3: Sleeping for 200ms to retry busy DB in the docker console log. Rebooting the container does not bring it back up and require a full system restart.
This does not happen every single day, and can go days without it happening and then boom locks up.

  • So far I have tried the following troubleshooting steps:
  • optimize database using plex gui
  • running plex-dbrepair container
  • restoring an old backup of my database from March 2026
  • moved from hotio to linuxserver container
  • disabled anything querying plex db e.g sonarr/radarr telling plex to scan for new content.

Currently I am running the following containers that “talk” to Plex
Kometa
Maintainerr (has been off for the last two weeks to see if that was causing issues) PlexAniSync
Posterizarr
radarr/sonarr
tautullii
tracearr
tdarr (which has also been off)

here is my docker container config (i do have a claim token but removed for the screenshot)

Here is a screenshot of the busy db error I will get, i have also attached my logs. I am not sure how to attach my databases as it says they are to large. 200mb is the zip downloaded from Plex. Any help would be appreciated, I have been pulling my hair out trying to fix this. And I’m at my wits end. Hopefully I have provided enough information.
