Have you ever checked the status of the processes (such as via top or ps with an "-o s" option) to see if they're in a D state? If so, they're in an I/O wait state and poking them via signal() won't wake them. They either timeout or you just pull the rug out via a reboot. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - IGNORE that man behind the keyboard! - - - The Wizard of OS - ---------------------------------------------------------------------- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
