Recently Plesk has hit a weird bug related to named.
Named remains down after a reboot & won’t start after attempting to start it in any condition throwing all sort of errors.

[root@testing ~]# /etc/init.d/named status
rndc: connect failed: 127.0.0.1#953: connection refused

[root@testing ~]# /etc/init.d/named restart
Stopping named:                                            [FAILED]

Here’s a fix for this bug, it may be a temporary solution but will work until it’s patched:

Execute these commands one by one.

1) cd /var/named/run-root/etc
2) mv named.conf named.conf.bak
3) cp named.conf.default named.conf
4) for x in `ls`; do /usr/local/psa/admin/sbin/dnsmng update $x; done;/etc/init.d/named restart

Here ‘x’ is going to be the file name returned by the ‘ls’ command for each file in the directory.
The last line of script is just a quick way to perform the dnsmng utility on all files in the directory and then restart named.
