WOW! Someone else with this problem!
Its doing this because you're logging connection attempts to ports that 
aren't listening. I don't know why the attempts happens. I get hundreds 
of these a day:
Connection attempt to UDP 127.0.0.1:50675 from 127.0.0.1:53
Connection attempt to UDP 127.0.0.1:54731 from 127.0.0.1:53
Connection attempt to UDP 127.0.0.1:54730 from 127.0.0.1:53
Connection attempt to UDP 127.0.0.1:54807 from 127.0.0.1:53

Strangely enough, mine are all to -> from locahost. Possibly because 
this box has a real address?

net.inet.udp.log_in_vain: 1

Whomever solves this one is my hero for life ;)
I think its a feature.
