Guys,
	run the following script nightly, and all will be well ... julius

#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
#echo $user

        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
