 Priority:  minor      |      Milestone:                  
Component:  Tor Relay  |        Version:  Tor: unspecified

-----------------------+----------------------------------------------------
 When Tor attempts to resolve a RR and receives truncated
 required, it gives up and fails rather than trying again over
 a TCP socket, as an example:

 tor-resolve test2.pho.be # works,
 whilst
 tor-resolve test1.pho.be # always fails.

 The problem seems to be in evdns.c / libevent
