On Cpanel server, found following error on /var/log/messages
Jan 29 15:15:50 server36 named[17870]: lame server resolving ‘bizhat.com’ (in ‘bizhat.com’?): 216.32.86.26#53
The problem is caused by some one pointing the domain to the server, but the account is not present in the server.
Problem is solved by disabling lame server loging in bind.
To do this, edit /etc/named.conf and add following line
logging {
category lame-servers { null; };
};
Now restart bind
service named restart
