      Got this crash on every login in a 1.20.4 server that had been working for at least a month. Not sure why it suddenly crashes.

      Upgraded to 1.20.6, same problem (but better backtraces in the crash report, at least).

      I know "Watching server" means the server is too slow/busy, I'm not sure how to find out why from the log...
