What is the maximum number of process which can run simultaneously in

I was testing with far fewer numbers than that, I was getting
exceptions in pthread_create

What architecture is this? On a 32-bit architecture with a 2MB stack size (which I think is the default) you couldn't possibly create more than 2048 threads just because of stack space requirements. Reducing the stack size would get you more.

I should also point out that any design that requires 40,000 threads is probably quite flawed unless you are running on a very large machine..
