Sounds like you've got some thread synch issue. On a mono-processor system, your threads are running serially, but on an SMP system (i.e. bi-processor) your threads are truly running in parellel thru the CPU. I'd take a good look at any data you're locking currently, or should be locking. It's hard to make more concrete recommendations without knowing exactly what the code looks like. -- http://mail.python.org/mailman/listinfo/python-list
