My guess would be a stack overflow, but without sample code and a terminal log it's impossible to be more specific.

Also, this should be posted in the Programming forum (http://forums.fedoraforum.org/forumdisplay.php?f=27), not here.

Is this a 32 bit system?

What exactly are you trying to do?

What exactly is the error message?

Try to monitor memory usage of your programs with ps or top.

Maybe try to upgrade to Fedora 16 or 17 which also have newer compilers and kernels with better threading support?

Also, is the array being shared by each thread or is a new array of that size being created by each thread. You could well just be exceeding memory in a big way with multiple threads.
