I'm trying to stop all (well most) processes on a server so I can do an effective single user dump, then restart them. Sending a SIGSTOP to a csh disconnects, sending it to a su'd shell stop the shell, but then sending a SIGCONT causes a HANGUP after stating the the pgrp has been reset, then reset again. Sending a SIGSTOP then a SIGCONT using /bin/kill works for su'd shell, so SUN must do something in /bin/kill more than just a kill(2) (ULTRIX does just do a kill(2) - nothing fancy in ULTRIX). So can anyone help? Jim. PS - forgot to mention, running 3.4 on a 3/280.
