When running chunky after a while my whole server would freeze with these logs https://mclo.gs/e2tO5CS. I have tried using JVM flags and it seemed to fix the issue https://stackoverflow.com/a/45461033 with no errors from the paper watch

This is not a bug. The behaviour there looks normal and expected. The issue is that your server is stalling for some reason when performing these checks.

Note instead of using that JVM flag you could also adjust chunky's worker count to the same effect (this is the 50 tasks you were talking about) as shown here.

Also see the FAQ for performance tips and join our Discord if you need more help with troubleshooting this issue. Happy to look into it more there.
