<pre>
$ drill  @2001:4860:4860::8888 aaaa leaf.dragonflybsd.org | egrep -v
'^(\;|$)'
Error: error sending query: Could not send or receive, because of network
error
</pre>

unless using TCP query:

<pre>
$ drill -t @2001:4860:4860::8888 aaaa leaf.dragonflybsd.org | egrep -v
'^(\;|$)'
leaf.dragonflybsd.org. 3599 IN AAAA 2001:470:1:43b:1::68
</pre>

Similar DNS queries on other boxes running different OSes don't have the same problem, and tcpdump output shows the response from the DNS server, so I doubt it's an network issue.

<pre>
$ uname -a

I also confirmed this issue on leaf, which running master as of Aug 4.
