Not a crash in the true definition (process crash) but a deadlock that rendered the server unusable after a while - leading to 503 errors
Jan 31, 2020 11:23:07.796 [0096] DEBUG - Completed: [64.136.236.218:57867] 503 GET /media/providers (4101 live) TLS GZIP 0ms 451 bytes
Jan 31, 2020 11:23:07.978 [2120] DEBUG - Completed: [127.0.0.1:62344] 503 GET /media/providers (4100 live) TLS GZIP 0ms 451 bytes
This shows how many requests got queued (4101 live)
Deadlock investigations are complex and require a process dump and also list of connections - so if this happens again - please get the connections list copied to a text file and then take a process dump of Plex Media Server.exe process and then capture the logs
See this post for diagnostics for deadlocks
