Reproducible Test

Im not sure what caused this, this is a failover server and no one was online at the time. The server was recently restarted. I haven't experienced this on the main server but that is running 1.19.4. I have included the whole latest.log in a Pastebin link in the anything else section just in case anything in there is of any use. The exception starts at line 183.

Anything else?
