Hi,

I have been experiencing strange problems with the
standard BIND install on my NetBSD/macppc box
recently. Here is a sample of the error messages I
see:

Oct 23 13:18:57 lulu named[112]: Malformed response
from [128.32.206.9].53 (query section mismatch
(ns.netbsd.org IN A6))

As you can see from the timestamps I get _lots_ of
these errors. According to the BIND error messages
list at
http://www.acmebw.com/askmrdns/bind-messages.htm, this
is due to "brain damage" on the remote server. This I
find hard to believe, given the quantity and
(presumed) quality of servers involved. Makes me think
something locally is corrupting the DNS replies.

Here's what I've tried in order to isolate the
problem:

- Disabled all services in rc.conf except dhclient (I
need this to connect to the net), named, and sshd.

- Changed my named.conf file (and zone files) to match
exactly the example specified in the NetBSD handbook. 

- Changed my named.conf to a forward only
configuration.

- Completely fresh install of 1.6 on a
newly-partitioned disk. (including example named.conf
config files from the handbook)

None of these have solved the problem.

I used to run NetBSD/macppc 1.5.2 up until a few weeks
ago when I upgraded to 1.6. After the upgrade I
started to get strange error messages from BIND. The
1.5.2 install worked just fine.

I should point out that everything mostly still works,
even with these errors. Queries take a little longer
to resolve, and occasionally fail, but for the most
part it's liveable.

So, any suggestions before I disable the standard BIND
and go to djbdns, or BIND9?
