Profile the app.  And, for you in particular, know how deep the recursion will 
go and hence how large one stack needs to be.

Also, can you move any data off the stack onto the heap?  This reduces your 
maximum stack size.

Re: Please help : StackOverFlow error

2008-01-07 Thread Benoit VARVENNE 
Hi Peter,

Thanks a lot. '-Xss' option works great.
Is there a way of determining what are "reasonable" values for the stack
size (maybe according to the potential number of threads, ...) ?
In fact I am not really used to such configurations...

Thanks again
Cheers,
Benoit

Check -Xss - this changes the stack size.  You might want to change this.
