It does appear to have deadlocked around 17:07 - but the load on the server was running high for quite a while and there may have been some hung requests from before that time
Deadlocks need specific diagnostics - getting list of connections and process dump as well as logs. I will give the details below
There has not been a recent deadlock fix released - however i think it is important to be running on the latest version available and i would recommend updating to 1.14.0.5465
One element of the diagnostics will be to force a crash report. I am concerned that your Plex Crash Uploader logs show some uncompleted crash reporting eg
Nov 10, 2018 11:09:22.414 [0x7ff93f90a780] DEBUG - HTTP requesting POST https://crashreport.plexapp.com
with no log entry to show that it completed the request to upload. So suggest testing out producing a process dump by doing a kill -SEGV <pid> where <pid> is the Process ID of the Plex Media Server process. That should crash out Plex Media Server and a crash report should be generated which may get uploaded on next restart. So what would be needed here is to test this out and after the restart check the Plex Crash Uploader.log and Plex Crash Uploader.1.log and see if the upload was successful
Diagnostics for Deadlocks on NAS/Linux
- Ensure debug logging remains enabled. (Settings / Server / General / Show Advanced)
- Ensure crash reporting is enabled. (Settings / Server / General / Show Advanced)
When you get the lockout (and please wait at least 10 minutes trying to access the server, before deciding there is a deadlock), do the following
in a browser get this request to this server
http://<local IP of PMS>:32400/connections?X-Plex-Token=xxxxxxxxxxxxxxxxx
Substitute the server token for the xxxxxxxxxxxxxxxxxxx
See this article for how to find the token
https://support.plex.tv/articles/204059436-finding-an-authentication-token-x-plex-token/
(This assumes your server remains on IP address 10.10.10.11)
Copy the response to a text file and send it to me by private message referencing this forum topic
Then get a process dump through the command line in Linux
kill -SEGV <pid>
where <pid> is the PID number for the plexmediaserver process
The crash report should get uploaded when you restart the server
Wait for few minutes and then get the logs zip and attach here. The crash uploader logs would give the information I need to locate the dump. The other logs would be needed for the investigation of the deadlock
[I just noticed your local IP is a WAN IP and there is no local private network range IP - so is this web hosted server? Remember never to disable remote access as that would stop access to the server)]
