TPS slow down followed by OOM crash

[Rektroth]

Describe the bug I run a dedicated server for my friends and I. For a few days, no one had been on the server, but the classic "Can't keep up! Is the server overloaded?" message started getting recorded in the logs every minutes... and then every few seconds... until finally C2ME crashed the server with an OOM error.

To Reproduce Steps to reproduce the behavior:

1. Run the server
   • java -Xmx12288M -Xms12288M -XX:+AlwaysPreTouch -XX:+DisableExplicitGC -XX:+ParallelRefProcEnabled -XX:+PerfDisableSharedMem -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1HeapRegionSize=8M -XX:G1HeapWastePercent=5 -XX:G1MaxNewSizePercent=40 -XX:G1MixedGCCountTarget=4 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1NewSizePercent=30 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:G1ReservePercent=20 -XX:InitiatingHeapOccupancyPercent=15 -XX:MaxGCPauseMillis=200 -XX:MaxTenuringThreshold=1 -XX:SurvivorRatio=32 -jar server.jar nogui
2. Wait for a few days with no one online

Expected behavior No slow down or crash.

Try reproduce without C2ME. And add -XX:+HeapDumpOnOutOfMemoryError as a jvm flag to your server.
