I had configured a local DNS server under F12 and everything was working

setup DNS again. Now I see the following errors.

I have 2 servers configured in the forwarders section of named.conf
forwarders { 68.2.16.30; 168.158.8.15; };
It only complains about the second one.
I found Bug 577639 which seems related, but it's marked closed notabug.
So if it's not a bug why am I seeing these errors and how do I go about
resolving them?
Is this a configuration issue on my side, or is this an issue with my ISP?
The file "/etc/named.iscdlv.key" contains the correct key.
Any assistance is appreciated.
Did you test if it is not related to selinux?
I don't believe it has anything to do with SElinux since the errors only
show up for one of the 2 DNS servers I have listed in the forwarders
entry. Also I don't get any SElinux alert messages.

May we see your /etc/named.conf file please?
I am wondering if you have an old /etc/named.conf file.
Please look for /etc/named.conf.rpmnew, and if it's there,
please compare the two files, save your current /etc/named.conf,
and mv /etc/named.conf.rpmnew /etc/named.conf
When I do,
[root@rsewill ~]# service named start
Starting named: [ OK ]
followed by
[root@rsewill ~]# host -a energy.gov localhost
<Too much stuff got printed to reproduce here without reason>
<Output looks reasonable>
I do not have bind-chroot installed. Are you using bind-chroot?
For this test, I am using
[root@rsewill ~]# rpm -q bind
bind-9.7.1-2.P2.fc13.x86_64
What version of bind are you using please?

I am using bind-chroot. As was using it under F12 also. I have
attached both the named.conf and the named.rfc1912.zones files.
What initially triggered the post was that suddenly all name resolution
stopped. If I bypassed my DNS server everything worked fine. I
restarted named and everything started to work again. When I looked at
/var/log/messages to see if there were any messages explaining why my
DNS server had failed I saw all these error messages.
