We hoped that FreeBSD 6 would have solved this problem after this thread on freebsd-stable : http://lists.freebsd.org/mailman/htdig/freebsd-stable/2005-June/016154.html I have just tested with FreeBSD 6-RC1 and the problem remains here. Moreover, I think it's also a security issue because a single user, with a shell account on an FreeBSD SMP box, could trigger a panic with a simple shell script like that one (posted by Marc Olzheim in PR 83375), it's annoying particularly in a multi-user environment : #!/bin/sh count=0 while true do screen -d -m -c "${PWD}/.screenrc.crashpts" & count=$(($count+1)) if [ $(($count%100)) = 0 ] then killall screen sleep 2 killall -9 screen fi done -- Philippe PEGON
