Bumping this thread as we have not received any responses

World IPV6 day was Jun 6
This problems started with the yum update below on Jun 18

/var/log/yum.log:Jun 18 06:56:33 Updated:
30:bind-chroot-9.3.6-20.P1.el5_8.1.i386

None of the 5107R or 5108R name servers exhibit this problem
It is possible the logging may ignore it.

latest bind on 5107R and 5108R
    bind-9.7.3-8
on 5106R - ns1.inscomp.net
    bind-9.3.6-20  - installed June 18


we added
  OPTIONS="-4" to /etc/sysconfig/named
and to /etc/named.conf - forwards are ISPs named servers
  forwarders { 12.127.17.71; 12.127.16.68; };
   // turn off IPv6
  listen-on-v6 {none;};

none of the above helps
This problem appears to exist on all 5106R name servers.
