Out of memory.

Does anyone know what could cause the following exception? I get this exception as soon as I run my application. I am using JRE 1.5.0_8. The problem is, some times I get this exception and some times not.

I can add to this an experience I once encountered. I noticed once my VM increasing a lot but the physical memory stayed the same. Any idea? I know the question is too broad, but I am trying myself to narrow it down.Thanks,
