    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 addr:(nil)
    Obtained 4 stack frames.

    #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?

    Hello,

    The -batchmode and -nographics options should not be needed for a dedicated server build.

    The "signo: 11" indicates to me that this was a SIGSEGV (segmentation fault), which is generally speaking a memory access problem. If you could post the whole log output from your game server, this could help to track down the source of the problem

    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.
