I'm quite certain it's not hung in memcpy since I'm highly confident memcpy doesn't have an undiscovered bugs. :) Instead it's presumably looping in receive_packet or at a higher level, possibaly in dispatch. At the very least I need a coredump and your executable so I can look at variables in receive_packet. Thanks for your report. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
