The most recent security upgrade for C-Panel is causing an issue for named on many of our dedicated machines.  You will find more information on the situation at http://forums.cpanel.net/showthread.php?t=55403&highlight=bind-libs

To correct the situation you need to make the following changes to your server:

Login to shell as root and open your resolv.conf (Resolver Configuration File):

nano -w /etc/resolv.conf

Add the following line to the bottom of resolv.conf:
nameserver 216.227.220.3

Note: Do not remove any of the other nameserver entries, or any search or domain entries, only insert the above line.

Ctrl+O (to save)
Ctrl+X (to exit the file)

This will give your machine access to internet to get the upgrade:

yum update bind-libs

This will begin the upgrade, it will ask you:

[update: bind-libs 20:9.2.4-14_EL3.i386]
Is this ok [y/N]:

at this point you will type in a y

Then restart the nameserver:

service named restart

and the issue should be fixed.
