And it always happens for exactly 4 minutes and 24 or 25 seconds. It fixes itself entirely on its own every time, but I'm not sure why. I thought it might be Plex doing a database backup, but as far as I can tell, that doesn't line up with my Plex scheduling, or Plex logs.

 

I'm not sure how long this has been going on, I only became aware of it because I recently started using a down detector, and Plex will become inaccessible at some point for 4 minutes and 25 seconds, usually overnight. But it just occurred outside the Plex scheduled task window, and the whole server machine slowed down, so I'm unsure what it could be.

Are there any periods within the time spanned by the syslog in the diagnostics you posted that you know this occurred to help narrow the search criteria.

Nothing in the syslog around any of those periods except for the fact that there appears to be no activity in the log for some time after the times you give as well.   No idea therefore what might be causing the symptoms you describe.
