AMP often crashes randomly

OS Name/Version: Linux Ubuntu 22.04.2

Product Name/Version: AMP 2.4.4.0

Problem Description:

Hello,
I have an active Minecraft server and my AMP often crashes at random intervals, sometimes there are hours between sometimes only a few minutes, and I can’t find a solution I found this error in the log but can’t solve it.

I replaced the Links with url because i am not allowed to post so many Links

I hope you can help me

Steps to reproduce:

  1. It is a Paper Server with some Plugins
  2. Sometimes when playing the server crashes

Actions taken to resolve so far:

  • uninstalled unused Plugins
  • allocated more memory
  • updated Paper and AMP

[08:38:10] [Logger Info] : Stop requested: SIGUSR1 Recieved

It’s not crashing. It’s receiving a deliberate, intentional request to shut down cleanly.

Thanks, that is good to know,
but i don´t have any idea why. This is my first server on Linux and i don’t know how to fix it

Actually something is going wrong, but what exactly is impossible to say. Have you checked the Minecraft logs to see if there’s a crash report in them?

I checked but the log from that point in time is 0 bytes in size, so it’s empty. But I looked again in the Spark plugin and it shows me 7.6GB of physical memory but only 1.7GB of memory for the process. I’m not sure if that helps, but I can’t find anything else.
