So I run a bukkit server and my server was a bit laggy, so I decided to up the RAM. When I tried to, it would not allow me: C:\Users\Zachary\Desktop\WaveCraft>java -Xmx2048 -jar -o true Error occurred during initialization of VM Could not reserve enough space for object heap Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. I do have a 64 bit processor, and 8GB of RAM. But I can't allocate 2GB for some reason. Help?
