>local7.debug         /var/log/named.log

...and, I hope, a line for the normal system log that contains something
like

*.info,local7.none	/var/adm/messages

Otherwise you will get all named's messages in both /var/log/named.log
AND /var/adm/messages.

Also, some mechanism for ageing the log files might be in order.  We have
as part of a script that runs every weekend (Korn shell script):

# Slide down old named logs
if [ -f /var/log/named.log ]
then 
    # slide the log files down
    mv /var/log/named.log.5 /var/log/named.log.6 2>/dev/null
    mv /var/log/named.log.4 /var/log/named.log.5 2>/dev/null
    mv /var/log/named.log.3 /var/log/named.log.4 2>/dev/null
    mv /var/log/named.log.2 /var/log/named.log.3 2>/dev/null
    mv /var/log/named.log.1 /var/log/named.log.2 2>/dev/null
    mv /var/log/named.log.0 /var/log/named.log.1 2>/dev/null
    cp /var/log/named.log   /var/log/named.log.0 2>/dev/null
    cat /dev/null >/var/log/named.log 2>/dev/null
fi

kill -HUP $(</etc/syslog.pid)
