Maybe I should have added some information about my server. Oops! :-)

I'm running a relay-node on a dedicated Linux box (Debian Wheezy/64bit). 
Those two 'strange' UDP ports are opened on both the current stable 
version and the latest alpha version of Tor.

My server is running fine(*) even with those UDP ports firewalled off. 
So they cannot be essential - but I'm still curious about their purpose.

(*) Well - if the switch from stable to alpha stopped those crashes, 
that is. Time will tell ;-)
