This has to do with the current DNS implementation in asterisk, which  
is not very asynchronus. we are working
on fixing this. While waiting for that solution (hopefully in the  
release after 1.4) I would guess that running a local
caching DNS server on your LAN would help. Asterisk will then get a  
DNS reply, even if it says "sorry, have no answer".
Sending DNS queries, not getting any response, kills Asterisk.
