Server was started and allowed to run unoccupied with no error.
After player joins server, there is a delay where the player can move about in the world, then the server crashes silently. Error persists after downgrading server to 1.14.1, then re-upgrading to 1.14.2. When the world is played in single player, there are no crashes.
Error has been triggered 4 times.
I'm not sure what would be required for reproduction other than the world folder, but as it is 913 MB in size, I will wait on providing it until requested.
Potential related bugs:
MC-138550 has lag leading to crashes, but there is no lag before crash in my scenario.
This is always caused by the server being heavily overworked and shutting down because of that. Hence, probably caused by MC-138550, even if you didn't notice any lag.
Please note that MC-138550 is about server lag, not client lag. Your FPS can be amazing, but this issue can still occur.
