script/command to kill processes running on particular port

I want know, "Can we write some shell script that will kill all the processes running on particular port.. I want to run that script daily by cron... " I have written a server that runs some port say 3001 on my Mandrake server.. Now I need to restart that server daily with cron.. but when I try to end that server, its processes running on port 3001 does not terminate.. I need to kill those processes and start my server again..
I hope I am clear..

Please help

Something like

lsof | grep IPv | grep 3001 | awk '{print $2}' | xargs -l -i kill -9 {}

should work ...
