Definitely sounds like bind-chroot is the culprit. I’ve had a few problems with it myself. Once you’ve removed it from your machine
|yum remove bind-chroot
service named start
add the following line to your yum.conf file under the [main] section
Is it safe to update system packages using the operating system package manager?
Yes, it is safe and moreover we recommend to use ‘yum’ (or ‘apt-get’ on Debian) to keep the system up-to-dated.
However some packages may conflict with Plesk or another software, they can be added into skip list. It is recommended to use the following settings:
– for up2date, add into /etc/sysconfig/rhn/up2date:
– for yum, add into /etc/yum.conf:
exclude kernel* sendmail bind-chroot caching-nameserver
