I was able to get back in the WebUi...for a short time... :|

Seems it had a restart thus I was able again to log in.

I extracted the relevant logs.

Is there any explanation for the restarts?

Does the volume resync after the restarts?

  The issue comes from clamav.
  After SEVERAL tentatives, I was able to get access to the WebUI, enable the SSH termina.
  Then after other several tentatives, and timeouts I was in the prompt...
  I used then
  ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem | head
  to get the process list, and the clamav process was eating most of the ressources (~92%).
  Plex instead was around 1%.
  
  Now I disabled the antivirus functionality, and I did not observed any hanging since 24h.
  
  In the log file there is no information about volume resync...
  Where I can get it?

    Look for "resilver" in the === maintenance history === section at the end of volume.log

    I suggest checking the fullness of the root partition. It's only 4 GB, and the system will misbehave in several different ways if it is getting full. Normally it's around 25% used.
