findns error (NXDOMAIN) on localhost?

I noticed that this question has been posted on this list in the last few
days/weeks, but I do not see any definite answers to this problem. Sorry
if I have just missed it, I would be grateful if someone could point it
out if that is the case.

I have noticed this error in the system logs from time to time over the
past few months but now it is filling my logs at an alarming rate.

May 31 13:20:41 6D:XXX named[17327]: sysquery: findns error
(NXDOMAIN) on localhost?

I am getting a couple entries of it every minute and when I did a dump of
the named db I noticed that the cache had quite a few domains who have
defined their ns as localhost. I also ran across syslog's similar to the
following:

May 31 13:20:41 6D:XXX named[17327]: sysquery: query(mx1.2cool2play.com)
Bogus LOOPBACK A RR (localhost:127.0.0.1) learnt
(A=localhost:NS=209.164.22.203)

I had not changed anything in my zone definitions for localhost for a
couple years (until after this problem arose) and I have included the
results of a dig on localhost which seem to indicate that that zone is
fine. I guess my question is whether the log entries of the NXDOMAIN error
are related to the second log entry that I listed above. If so, is there
any way that I can prevent the server from learning this incorrect
information "learnt (A=localhost:NS=209.164.22.203)"? If not can I at
least keep the server from logging the error without loosing other
valuable log information.

Thanks, Cale.
