Error: named restart failed

[SanTi]

Hi, I'm having the same problem but I just found the solution

check how many bind* are installed on your server
yum list installed bind*

Installed Packages
bind.x86_64 32:9.8.2-0.47.rc1.el6 @base
bind-chroot.x86_64 32:9.8.2-0.47.rc1.el6 @base
bind-libs.x86_64 32:9.8.2-0.47.rc1.el6 @base
bind-utils.x86_64 32:9.8.2-0.47.rc1.el6 @base

if you see bind-chroot then this cause problem
yum remove bind-chroot

restart the named
service named restart

I don't see bin-chroot
named still failed to start

Update : Just share when you got the same error with me and still not start with above solution
It maybe different log error on me, but I solve when I detect there are 2 record duplicated on "www" with A and CNAME

Here my error failed start with "service named status -l"
