copied directly from the CMD cause i dont know better..



no machine details cause i dont think its something specific for me

am also using this script to launch it ( works perfectly on a vanilla server )

&quot;%ProgramFiles%\Java\jre6\bin\java.exe&quot; -Xmx2G -Xms1G -jar Tekkit.jar nogui

pause

this is just a question, not a bug report.. for i suspect im doing it wrong.

if however it is a bug ill provide all relative info.. just be nice, this kitten bites tyvm in advance.

you're right, you're doing it wrong. it also has nothing to do with using 64bit java (which you should have been doing all along if you're on a 64bit machine, but that's not the point).

the bug board has your answer in a sticky.
