Perhaps it's time to add more memory to your machine. If you've already maxed out your memory, then maybe it's time to get a machine that can use more memory and use a 64 bit OS so you can use all the RAM you add to your machine.

...or you could change your program to use less RAM. But since I can't see your program, you'll have to figure that out yourself.
