I have got a problem. My program is really big and java is throwing OutOfMemoryException.
In .bat file, I have got the following:
java -server -Dfile.encoding=UTF-8 -Xmx1500m -Xbootclasspath/p:../libs/l2ft.jar -cp config/xml;../libs/*; l2ft.gameserver.GameServer
Java is using 6 GB of my RAM, next 6 GB is not used.
I typed System.getProperty("sun.arch.data.model"); and it says that I am using 64-bit JVM.
You have set the maximum heap size to 1500m and while the JVM can use a little more than that ~200 MB, that’s all you limited the process to.
Try instead to limit your progress to around 5 GB. (You want to leave some memory for overhead and the OS)
