dns requests from localhost to localhost

I recently (all the time actually - ever since installing my BIND) get these log entries:

Nov 12 22:47:18.100 client query: . IN A
Nov 12 22:47:48.301 client query: . IN A
Nov 12 22:48:18.510 client query: . IN A
Nov 12 22:48:48.710 client query: . IN A
Nov 12 22:50:19.321 client query: . IN A
Nov 12 22:50:49.530 client query: . IN A
Nov 12 22:51:19.730 client query: . IN A

I have no idea what that is... there is no process number "3015" nor is there a port open on 3015...

I just don't know what that is.

any help is greatly appreciated.

well the number 3015 is the port number used by ur name-client not any daemon
i think there might be some local services that is responsible for generating these queries,
so check out for the possibilities of any local services and try to find out the response of dig localhost
that will give u an idea about any potential zone file mistake

found out what that was....

it's the shipped NANNY Perl script. it makes sure the named stays running.
one of the tests it runs to check if the name-server is responding is:
dig +short . @localhost > /dev/null
this was the reason for the odd logentries.

OK, then is there a way of logging everything except "...client query: . IN A.." like regexp?
