as you know, udp has no guarantee of delivery (or ordering for that matter). so if there are any network issues whatsoever you can lose udp packets pretty easily; tcp packets will resend when they aren't ack'd. if you need guarantees with udp you usually end up setting up some sort of ack-on-failure (as opposed to tcp's ack on success which suppresses a resend). welcome to udp =) -- Aaron J.
