recursive aaaa lookup errors?

[Rick Dicaire]

Hi folks, bind 9.7.1, dnssec enabled and using dlv, bind built with

./configure \
  --prefix=/usr \
  --sysconfdir=/etc \
  --localstatedir=/var \
  --mandir=/usr/man \
  --enable-threads \
  --enable-ipv6 \
  --build=$ARCH-slackware-linux

on a Slackware 13.0 32 bit machine. This servers use is recursive/cache only.

I'm getting the following in syslog, only appears to be happening with
AAAA lookups:

What is the cause for these errors?

Thanks
