RQ is *received* queries, which implies that some *other* machine is
sending queries to named, not that named is doing something.

My guess is that you have a mail server configured to process its queue
every hour.  So every hour it goes through its queue of spooled mail,
looking up the MX records of all the destinations, which involves querying
your nameserver.
