How can I troubleshoot server overload warnings on my Raspberry Pi 4 Minecraft server using PaperMC?

Question

I opened the minecraft server using raspberrypi 4B model which has 4GB ram I allocated 3GB to server and used the paperMC to open server. Also I formatted to rasberrypi OS 64 bit version.

It works well, but sometimes the server connection was lost. and this is the error message printed on the cmd of raspberrypi.

How to find the problem of this?

I want to reopen the server.

Answer 1

Maybe try less ram? `java -Xms2G -Xmx2G -jar paper-1.19.4-538.jar' Also turn down the amount of ram going to gpu by "Running 'sudo raspi-config' from terminal > then select Advanced Options > Memory Split > update the number to 16 > save it & restart the Raspberry Pi."
