Why are you running a dev build here?

aws0jam commented 1 year ago

Because of luckperm support.

desht commented 1 year ago

FTB Essentials 1902.3.3 as published on CurseForge includes luckperms support, so please use that. If you're still seeing the problem then, I'll take a look.

While you're welcome to build and use dev builds, please do not raise issues against them. If you're building and running your own dev build, you're expected to be able to debug issues yourself.

This one might be hard to track down, since I can't reproduce it, and I can't see what in the code would cause a CME. CME's can generally open happen if there's multithreaded access going on (there isn't here), or if something modifies the hashmap during iteration (again, not happening).

I've made an experimental change which isolate all modifications to the hashmap to the tick method, which you can try out - get it from https://maven.saps.dev/releases/dev/ftb/mods/ftb-essentials-forge/1902.3.4-build.101/ftb-essentials-forge-1902.3.4-build.101.jar

Can't guarantee it'll help, but even if not it might provide some more clues as to what's happening.

Just checking if you've had a chance to try that dev build?

I can reproduce this on my TNP LL7 server consistently, on v18 it crashes whenever a player teleports from another dimension (nether) into another (overworld) with warmup enabled.

We primarily use /home to get back from the nether but /tpa and /back also cause the same issue. It seems to happen 1/10 times when a single player is teleporting but it happens 100% of the time when multiple players are teleporting and one of those players is tp'ing from one dimension to another.
