Although this prevent packets from being passed
up to the app, you may want to just to turn the
service off, especially if you don't know what
it is.

Assuming you don't own the process, try a 'netstat -lnup'
(which lists listening udp sockets) as root, look for the
pid of the process that owns the socket, and KILL it.
You may even be kind enough to send it a TERM sig first.
And then disable the startup script for the service.
