We have already resolved some of these. The logs you provided Plex Media Server Logs_2020-02-10_16-12-04.zip are from 1.18.5.2309-f5213a238 showing the issue that has already been fixed in 1.18.6.2368
See release note for 1.18.6.2368
- The server could become unresponsive after navigating many preplay screens
There was also a performance related fix in 1.18.6.2348 where the issue was leading to server unavailable sometimes
- (Performance) Speed up connectivity tests and library discovery (#10930)
Would like everyone with these hangs please update to 1.18.6.2368 and let me see logs after a restart following a hang. If there is a deadlock situation, would then ask for additional diagnostics - for list of connections (from GET /connections) request and process dump - but will only ask for that if the logs do show a deadlock
