Server crashing without an error message

[poperigby]

I'm a having a lot of trouble diagnosing this crash, but it appears to be something to do with the server overloading.

compose.yml:

  app:

    hostname: minecraft

If it created one, you might need to look at the crashlog file that Fabric (and other) server writes out.

I'm pretty sure it is since I have seen others encounter this situation with no indicator of why it stopped.

That's strange, because free is showing 9GB of available RAM when MC isn't running.

               total        used        free      shared  buff/cache   available
Mem:            13Gi       3.3Gi       5.5Gi        51Mi       4.8Gi         9Gi
Swap:          511Mi       511Mi          0B

Not sure what to say about that 🤷‍♂️

In the startup script, before the Minecraft server is started, it is calling free to produce that output:

docker-minecraft-server/scripts/start-finalExec

Line 198 in 0f85646

free -m

...oh, I'm sorry, I was mixing up free and available, even though that's what you stated. In the original output it shows 10GB available.

I'm still out of ideas unfortunately. I'm hoping someone else can help out.

No worries. It's an easy mistake to make. Thank you for your help.
