I am getting the same error every time new chunks are generated... Maybe its a to slow Server? Mine is normally fast enough but from time to time when several players are online the server gets some trouble ...
It´s the first time I´m trying to understand a crash report but I tried to generate the world before I opened it for everybody...
I installed worldborder set the border up to 4000 and filled the world ( "/wb fill ")
It is a very long progress and i made it at home on my own PC over night because if there are any errors or problems its easier to solve and easier to control the progress... then i uploaded everything...
now everything is working fine and I am using multiworld.
One spawn/home world and one dungeon world witch I replace every two weeks with a fully generated world...
At least i didn´t find a real Solution but a possibility for a smooth gaming experience. But maybe for bigger server not a possibility.
Sorry for my bad English but I hope I could help.
