Plex Docker - Socket not connected

[ez009]

Hi, I've had this reoccurring problem for several months now.
Plex is the only thing running other than Unassigned Devices that have 2 disks mounted for schlepping files.
I'm running Unraid 6.12.0 but this was happening in prior versions as well.

Every 2 days, Plex stops functioning and I get lots of these in the Plex log:

Traceback (most recent call last):
  File "/usr/lib/plexmediaserver/Resources/Python/python27.zip/logging/handlers.py", line 76, in emit
    if self.shouldRollover(record):
  File "/usr/lib/plexmediaserver/Resources/Python/python27.zip/logging/handlers.py", line 157, in shouldRollover
    self.stream.seek(0, 2)  #due to non-posix-compliant Windows feature
IOError: [Errno 107] Socket not connected
Logged from file agentservice.py, line 786

It requires a reboot to fix. Stopping and starting any dockers immediately after the issue
results in "Execution error, Server error"

In prior session where this happened I did see "Transport endpoint is not connected"
However today I just see "IOError: [Errno 107] Socket not connected" in the Plex log.
I've looked at similar threads like these and I've disabled NFS which was only present on the Unassigned devices, but that did not fix it.

and this

Here are diagnostics from today's event, saved right before reboot.
Any help appreciated, thx.
