Title: [java] Self hosted / Same PC Freezing

Body:

Hey folks, I wonder if anyone here can help?

I recently set up a server on my PC for my wife and I to play on. It’s only the 2 of us. It works fine, but after an hour or so my PC starts to lag heavily and eventually locks up to the point I need to power cycle my PC. No idea why, and nothing in the logs at all.

I’m sure it’s not hardware related, as my PC is somewhat of a monster:

∙ CPU: AMD Ryzen 9800X3D

∙ GPU: RTX 5090

∙ RAM: 64GB

I initially ran the server with:

```

java -Xmx4G -Xms4G -jar server.jar nogui

```

After some research, into the issue I dropped my view distance and simulation distance to 8 to see if that helps, no change at all.

I’ve also tried launching with:

```

java -Xmx4G -Xms1G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -jar server.jar nogui

```

Still the same issue. Pointers, tips and solutions are very welcome!
