> what do i do?

[Zebz213]

Add more ram (1GB for you and a friend or two, 2GB for a small server, and 3GB for a normal server). If that doesn't work redownload Tekkit server software and try again.

There is a sticky about your problem, did you try the solutions in it?

No.

Try updating your Java. Chances are you're using an older version. If that doesn't work, head over to the tekkit bug report forums and make a report so we can get more info out of you.
