Modpack version

Crash log: https://pste.ch/efapejoloy.pl

Describe the bug

On breaking the the JAMD portal block while in the mining dimension (because OCDs prefer said block in the flooor, ahem), the hang-check timer kicked in and killed the server. Nothing of note in latest.log/debug.log. Crash report attached.

This is on a multiplayer server btw.

Steps to reproduce

  1. Portal through to the mining dimension
  2. Break the portal block
  3. Wait 60+ seconds for crash/profit

Expected behaviour

No crash

This might be more of a user error than a bug, unsure...

Been trying to reproduce this to get more detailed logs when I got the following OOM error on the console:

[21:18:30] [Server thread/WARN] [minecraft/MinecraftServer]: Can't keep up! Is the server overloaded? Running 9635ms or 192 ticks behind

Turns out I'd lost my more sensible -Xms/mx options in user_jvm_args.txt when upgrading from 1.0.0 to 1.1.0. Now, while running with -Xms/Mx set to 4 and 6G, respectively, I can no longer reproduce this crash.

Yeah, this wasn't a crash because of the mod in question, this was a server misconfiguration, easily done, glad you've got it fixed
