High named CPU every 10 minutes?

The FreeBSD base system BIND is there primarily to provide a local
resolver. In the event that you are doing more serious DNS work (such as
authoritative DNS, a resolver for the local network, etc.) the
expectation is that you will update to a more recent version of BIND.
Using the ports this is quite easily done, and all you have to do in
rc.conf is to change named_program to /usr/local/sbin/named.
I recommend that you install /usr/ports/dns/bind97.

Nothin' ever doesn't change, but nothin' changes much.
