So both times dynmap broke the past week it was caused by someone going through a randomly spawned dimension door I believe? It is a known bug apparently, but no fix yet: https://github.com/webbukkit/dynmap/issues/1278
I was hoping dynmap was a separate service that could be restart without taking down the service but it appears it is a .jar plugin...so maybe we have to take the entire server down to fix? There are still potential solutions, from easy to harder:
- 5AM daily restart of server
- Can we watch the log (linux `swatch` util, windows should have something like it) to trigger an auto restart?
- Detect any time the map breaks and alert "Server will restart in 1 minute to fix map", then restart the server.
- Can we unload/reload the dynmap module to prevent causing downtime?
- Can we query the server to check if there are 0 players to it knows it can restart without pissing people off?
