Are you using daemon threads? There are some issues with CPython when exiting with daemon threads: http://bugs.python.org/issue1722344 http://bugs.python.org/issue1856 http://bugs.python.org/issue4106 It's possible you are encountering this kind of problem. I have had to deal with issue4106, the workaround being to explicitly join the thread of multiprocessing.Queue before exiting. I would follow Scott's advice and explicitly request and wait for your threads to exit before terminating the process. -- http://mail.python.org/mailman/listinfo/python-list
