Hi! It's been days that sometimes, when I connect, not everytime, my server crash a few minutes after. I don't understand why and it's getting frustrating. 

Here is the full crash report :

https://pastebin.com/QbSvWEiZ

Use Java 17 instead of Java 21

I changed the version to Java 17, but it still crash the same way with the same error. :/

Add the latest.log from the logs folder

Here is the server log from starting to crash, then

https://pastebin.com/d7qXQS1Y

The server crashed after a //paste command

I think it is a server RAM issue - log or crash do not show any RAM allocation, but other JVM Arguments - so the -xmx argument is missing

Set the RAM allocation by adding -Xmx4G to the server arguments

I don't have access to JVM arguments on my dedicated server on OMGserv, what should I do? My server is actually at 11180 Mo in RAM and 59% CPU

I missed critical informations

Maybe contact the server host/support

the support said it's worldedit

Yeah – we already got this far here too ...

You are using the forge worldedit build

You can try to use the plugin Worldedit or FAWE as your server supports plugins

https://www.spigotmc.org/resources/fastasyncworldedit.13932/

support is telling me about map corruption since worldedit "makes crash" at connection, but I don't know what to get out of that information

I double checked and I'm using the worldedit plugin, the worldedit mod isn't even in my mod folder

since I'm using worldguard, the plugin one is mandatory

also, the server didn't crash since November 2, since I put Java 17, it crashed 2 times and didn't crash yet since, maybe it's important information.

missed worldguard info, and actual situation

Make a test with replacing worldedit with FAWE
