Server occasionally freezes – Docker containers inactive, reboot via WebUI not possible

Featured Replies

Hi everyone,

I'm experiencing an issue with my Unraid server (latest stable version) where the system occasionally gets stuck in an unresponsive state:

  • The array is started
  • No Docker containers are running (all appear stopped)
  • CPU load is very low
  • The WebUI is accessible and navigable, but somewhat sluggish
  • Rebooting via the WebUI (or even via reboot in the terminal) does not work – the system seems to hang during the process
  • I'm forced to do a hard reset via the power button, which is obviously not ideal.

 

The issue happens sporadically — sometimes after a few days, sometimes within hours — and I haven't been able to pinpoint a cause. It might be related to Docker or a plugin, but I haven’t found any clear evidence.

 

I've attached a Diagnostics ZIP file, taken shortly before the last freeze, hoping someone can spot anything unusual in the logs.

 

Thanks in advance for your help!

Best regards,
Kevin

Regular syslog starts over after every boot, enable the syslog server and post that after the next crash.
