Bug Caught fatal signal - signo:11 code:0 errno:0 addr:(nil)

I am trying to run my dedicated game server on Multiplay.
I am using Unity 2021.3.10f1 to create the linux build.

The Test allocation works and I can connect to my server. After a few minutes the server crashes with the following error:
Caught fatal signal - signo:11 code:0 errno:0 addrnil)
Obtained 4 stack frames.
#0 0x007fded3b8e420 in funlockfile
#1 0x007fded23fb45c in mono_threads_exit_gc_safe_region_internal
#2 0x007fded23fb5e7 in mono_threads_exit_gc_safe_region_unbalanced
#3 0x000000420a6c23 in (wrapper managed-to-native) Unity.Collections.LowLevel.Unsafe.UnsafeUtility:MemSet (void*,byte,long)


When building with the target platform "Dedicated Server" do I still need to add the parameters -batchmode and -nographics to the configuration?

 

Thanks for the quick response!
I attached the log file to this post.

I had overlooked that one of my scripts did produce some Null Reference errors. I fixed this, switched to dedicated GameServer as build target and now it seems to run without crashing.

 

Almost the same here without any solution :
