It's most easily reproduced like this: - Program syscons(4) for a visual bell: kbdcontrol -b visual - Start some output intensive job on some VTY: strings /dev/urandom - Switch to another VTY and issue a bell: printf '\007' - Watch the job in the other VTY has stopped, and see that VTY state in the ``pstat -t'' output.
