Run the Minecraft server within Ubuntu server Proxmox VM
Problem Description
Issue
A few minutes after starting the server Ubuntu crashes completely, saying “out of memory” and not responding to restart or shutdown signals in Proxmox. The AMP webserver also stops running. The physical server has 16GB of RAM, the VM is configured with 14.65GB of RAM, and the Minecraft server is configured with 8000MiB. Not sure if it’s a configuration error on my side or not, apologies if it is.
Reproduction Steps
Created Ubuntu Server Virtual Machine in Proxmox
Installed AMP and configured first Minecraft server
Wait for about 10 minutes after starting up, then it crashes
Nah, but I would suggest testing briefly without the mods, see how a plain Fabric server runs. (easiest would be to rename the mods directory in AMP)
It would at the very least tell you if the mods are causing the issue.
(Take a backup of the world if you have any progress on it)
did this and it crashed immediately when I started the server. After restarting the VM it worked, but it felt really laggy and said “Can’t keep up! Is the server overloaded?” every few seconds with a single player online. The VM has 32 Xeon e5-2697a v4 threads assigned so I don’t think it’s a hardware issue.
Used an older version of the modpack which fixed all of the performance issues and hasn’t crashed yet, likely user error from the mod configuration. Hopefully working now, thanks for the help!
edit: let it run overnight and it did it again, here’s a screenshot of the terminal
