A number of bugs giving rise to deadlocks have been fixed already with two separate fixes going into 1.13.4.5251 - I am aware that there is still a deadlock bug in 1.13.4 and we are waiting for the diagnostics so it can be investigated and fixed.

Deadlocks can only be investigated from process dumps together with logs with debug logging enabled and also a list of connections at the time.

The snippet of log you found would be for actions that are not impacted by a deadlock

Please could you follow the steps outlined below so that the problem can be identified and fixed

Diagnostics for a deadlock / lockout (Windows)

  1. Prepare yourself by finding the server security token string as it will be needed for the connections list request. To find the token string, see this support article https://support.plex.tv/articles/204059436-finding-an-authentication-token-x-plex-token/
  2. When the problem occurs (and please wait for sufficient time before capturing diagnostics or restarting eg 10 minutes of requests to the server not getting through) , get the output from a specific browser request on the server. In a browser, go to this url http://localhost:32400/connections?X-Plex-Token=xxxxxxxxxxxxxxxxxxxxx where you put the server token string instead of the xxxxxxxxxxxxxxxx. Copy the displayed output to a text file and save
  3. Next is to force a process dump for the Plex Media Server.exe process. We can do this with Windows Task Manager - but on a 64-bit windows and with Plex Media Server.exe being a 32-bit application, you would need to load the 32-bit x86 version of windows task manager. So load this program instead of the default task manager C:\Windows\SysWow64\Taskmgr.exe
  4. Using this 32-bit Taskmgr.exe find the Plex Media Server.exe process, select it and right click on it and choose Create Dump
  5. Check that the dmp file has been created
  6. Restart the server and capture the zipped logs
  7. Zip the dmp files and upload to dropbox or similar service
  8. send me by private message link to the zipped dmp files and send the saved /connections output text files and the zipped logs
