Hi Thor,

Thanks! You've uncovered an interesting bug which was quite devious. It has
been solved in http://wiki.powerdns.com/trac/changeset/2150

The problem was that powerdns would indeed try to serve infinitely large
answers over TCP/IP, even though TCP/IP answers are still limited to 65KB.

However, since yesterday the domain auinmeio.com.br appears to have
developed its own problems, so it still does not resolve, but for a new
reason. It looks like it is just broken.

Can you verify using
http://svn.powerdns.com/snapshots/pdns-recursor-3.4-pre.tar.bz2 ?

	Bert
