Okay, I found the anwser. The -Xmx option works. If I set it to -Xmx128, 
then the memory value drops to about 310mb; if I set it to-Xmx64m, then 
the memory value is about 250mb. I think it's CBX that is eating up too 
much memory.

I feel sorry that I think it help prove 'FC3 sucks' topic. :-(

This is the end of this topic for me.
