Problem with java?

[The Doctor]

Pictures of what?
The client..closes. Doesnt give me a chance to stop it, just ends itself when the CPU usage gets to high :[

Try this.

64 bit OS

Code:

"%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xms600M -Xmx600M -YOURJARFILE.JAR

32 bit OS

Code:

"%ProgramFiles%\Java\jre6\bin\java.exe" -Xms850M -Xmx850M -YOURJARFILE.JAR

It will limit the java program to 850MB RAM maximum so it wont even try to use up any more.
