On my machine, I'm running a private modded minecraft server running Forge for Minecraft 1.7.2. My fiancé can play without any problems on my server, however when I'm playing I crash after about 10 minutes of play, either Minecraft says it ran out of memory or it just freezes up and stops working.

After some observation in the debug screen, I noticed that the RAM usage keeps climbing even when not doing anything. This happens in Single and Multiplayer.

My server uses the following batch file to launch:

java -Xms2048m -Xmx2048m -XX:PermSize=128m -jar ForgeServer.jar nogui

My client uses the following JVM Arguments:

-Xms2048M -Xmx2560M

The Java version in question is Version 7 Update 55

My server is using the following mods:

Applied Energistics 2   | Beta 17
BiblioCraft             | 1.7.1

WAILA                   | 1.5.2a
Witchery                | 0.18.4

I tried disabling Toxic Rain and VoxelMap, because I thought they'd use the most memory. But to no avail.

Does anyone happen to know why this happens?

Unfortunately, these crashes produced no crash log.

Turns out that Biomes O Plenty was the culprit. It's too unstable right now.


try this @ECHO OFF SET BINDIR=%~dp0 CD /D "%BINDIR%" "%ProgramFiles(x86)%\Java\jre7\bin\java.exe" -Xincgc -Xmx1G -jar ForgeServer.jar nogui PAUSE
