When you fly around a world and cause many chunks to load the server crashes.
I attached a log file.
I dont know if this has something to do with the crash, but sometimes the server says "Can't keep up! Is the server overloaded? Running <X>ms or <Z> ticks behind" even if noone is on the server.
The crash also occurs with no plugins installed.
Thank you for your report!
However, this issue is Invalid.
Your game, launcher or server is modified.
If you can reproduce the issue in a vanilla environment, please recreate the issue.
Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
Any plugin issues need to be addressed to the creator of the plugin or resource pack.
If you have problems on large servers, such as The Hive and Hypixel, please contact them first as they run modified server software.
