Hello FB, Thank you for responding to my posting. I have tried your suggestion, making a function rather than a method in a class. The result is still the same. According to the documentation, objects to be sent through 'Connection' must be pickable. But I couldn't find anything that explain the situation I'm having. I will report this to Python bug tracker. That way, the developer of multiprocessing module can try the test case by himself.
