query (cache) denied messages

[blrmaani]

I upgraded to BIND 9.3.2 from BIND 9.2 recently and started seeing
these messages in syslog. These message are filling up my syslog.

client A.B.C.D#yyyy : query (cache) 'blahblah/A/IN' denied

My DNS server is configured as Authoritative Name Server with
recursion=no.

I can't afford to change my named.conf now. Can I  fix using some
logging
category?

thanks a lot
