bind9 in debian 7

[Gregory Nowak]

Hi all,
is anyone else here running bind9 under debian wheezy amd64 as an
caching/authoritative server using ipv6? If so, are you finding it to
be stable? I'm asking because bind9 under wheezy seems to be crashing
one of my machines. Most times it will happen when starting bind9
during boot (the machine crashes right after the message starting
bind9). Other times it will start, but crash anywhere from a few
minutes to a couple of hours after. I found that when starting named
with the -4 flag the machine consistently boots to the login prompt,
and stays up so far. I've seen reports of bind crashing boxes when
trying to contact root servers over ipv6, but haven't specifically
seen anything naming wheezy as a distro where this happens.

Also, bind seems to crash the box when /etc/resolv.conf has 127.0.0.1
(or ::1) listed as a nameserver. This is regardless of if bind is
started with -4 or without (if it gets that far). Doing normal
dig queries works fine, but I've been able to consistently cause it to
crash when running

apt-get install chkrootkit

and

apt-get install cracklib-runtime

if using 127.0.0.1 or ::1 as the name server. It gets as far as
"working 0%," and the box crashes. Running apt-get install
... completes just fine if using isp-provided name servers in
resolv.conf. Unfortunately nothing shows up in the logs when these
crashes happen, so that's all I have to go on. Thanks.

Greg
