I updated to the newest changes from an hour ago and the server seems to eat all memory and OOM.

I noticed this as well in my pr that was going to add the same flags: https://github.com/NATroutter/egg-hytale/pull/16#issuecomment-3747095241

Best bet right now is to set -XX:UseG1GC instead of ZGC and remove -XX:-ZUncommit (G1GC doesn't use this flag)

Using -XX:+UseG1GC seems to give me much more stable memory usage as well.

Yes did this last night and seeing a big improvement.

OOM only seems to happen on generation of new chunks and calms down once complete.
