Description and relevant errors: Sometimes when players joins the server it almost crashes due to this error. It creates terrible lag and is apparently associated with some memory problem. I even had to edit the "memory=" parameter in the log file to be able to paste the error. It had about 320.000 zeros in that line.

We're using the latest Spigot 1.13.2.

Java version?

Still no solution to this? It still happens on all my servers.
