Machine is Athlon 1500+ with the 512MB RAM.

If you have multiple threads, the memory will exhaust on thread creation.

Quote: Why You need -Xss to 64m are you using lot of thread locals? If you have multiple threads, the memory will exhaust on thread creation. Nirav That is one of uncleared facts. In a code, I created only one thread (when I show print dialog), but in a NetBeans profiler I was surprised with a 12-15 threads. So I don't no, in a practise, what is the optimal setup for that number of thread, on the average machine (128RAM)..

Why dont you remove (or reduce) -Xss parameter.
