Hi Jerry, Is there an example you or someone can provide, if the thread is hanging, I would just like the thread to "return failure or timeout" and ignore the system call. Let the system call hang and I'll clean it up afterwards at the very end of the script.

From the POD (note the third bullet): NAME pool.pl - Simple 'threads' example DESCRIPTION A simplistic example illustrating the following: * Management of a pool of threads * Communication between threads using queues * Timing out and cancelling threads * Interrupting a threaded program * Cleaning up threads before terminating However, if the 'hung' threads are stuck on some system call, then the above will not work because of Perl's "safe signals". You'll need to read the section called "Deferred Signals (Safe Signals)" in "perldoc perlipc".
