DHCP + DNS não funcionou !! /etc/named.conf:18: couldn't add command channel 127

Caros amigos, configurei o DNS e o DHCP para que hovesse a atualização dinâmica do meu dns, mas isso não ocorreu. O meu DNS funcina normalmente e o DHCP também, mas eles não se cominicam "/etc/named.conf:18: couldn't add command channel 127.0.0.1#953: address in use" acho que essa mensagem é a resposta do problema! vou colocar abaixo o log,
Na ocasião dos testes o arquivo

-rwxr-xr-x 1 named named 1010 Jul 2 19:57 named.conf*
-rw------- 1 root root 1151 Jul 2 19:35 dhcpd.conf
