I truss the process running the POP tcpserver, then the process it forks when I connect to the POP port. I don't know if the ERR#9 is fatal, and unfortunately can't trace the next forked process 33323 because the child crashes immediately after displaying the info. Does this help at all? Thanks. mahe# ps -axww|grep tcpser 33265 ??
