Well, F. and Jim, GDM doesn't always clear the sessions gracefully, but
KDM has other "interesting" problems. Here is a qickie solution to what
ails F. - run the following from cron every night and you won't have to
call the doctor in the morning ;-)
#kill old leftover processes - all of them
users=$(awk -F":" '{if ( $3 >= 500 ) print $1}' /etc/passwd | grep -v -e
smb -e ^nfs )
for user in $users
do
processes=$(ps -ef | grep ^"$user " | grep -e Jan[0-9] -e Feb[0-9]
-e Mar[0-9] -e Apr[0-9] -e May[0-9] -e Jun[0-9] -e Jul[0-9] -e Aug[0-9] -e
Sep[0-9] -e Oct[0-9] -e Nov[0-9] -e Dec[0-9] |awk '{print $2}')
for process in $processes
do
kill -9 $process
done
done
