Running modded server with 6 people

Problem Description
Server crashes after ram gradually climbs to max

Issue

After starting the server and players start joining. Ram usage starts gradually climbing until the server reaches limit and crashes even if players aren’t doing anything to run up server usage

Reproduction Steps

  • Start the server
  • Players start joining the server
  • Ram gradually climbs until server crashes
2

That’s pretty normal if you don’t have scheduled restarts to clear up memory leaks.
Just something you need to do when working with some modpacks.

3

Problem is that it happens in the span of 20min after server restart

4

You’ll need to diagnose the issue with something like Spark (good for profiling), or talk to the modpack creators.
