Error when start named

[Rodrigo Faria Tavares]

Hello,

I try start named, come this error.

root at localhost chroot]# /etc/init.d/named start
Starting named: 
Error in named configuration:
/etc/named.rfc1912.zones:10: zone '.': already exists previous
definition: /etc/named.conf:35
                                                           [FAIL]

How I can resolve it ?
