The minecraft server randomly lags and then restarts

Problem Description

Issue

After playing for a while, the minecraft server randomly lags, then restarts and rolls back a little, monitoring the metrics everything looks fine, the server rarely consumes 3GB of RAM and the CPU is at most bellow 50%, (only goes into around 100% when restarting), so i don’t really know whats going on and the logs don’t have anything relevant for troubleshooting

Reproduction Steps

  • Open the server
  • Play for a while
  • After some time, the server lags
  • The server restarts
2

You can use the Spark mod/plugin to diagnose server resource issues. If there’s any crash reports you could look through those too

After running spark for a while, the only “bad” metric seems to be the max MSPT, which is around 100
