I have a process which creates a thread every time it is asked to process a
request so it is always ready to accept a new request.  After it process 256
requests - creating and closing 256 threads, it is not able to create
another thread and hangs on the create thread process.  The existing threads
have all completed and exited out and when I check the process they does not
appear to be any threads left running.  Has any one else run into this and
if so, is there any type of solution other than shutting down and restarting
the main process which created the threads ?

Troy.
