DNS Root server updating auth zone

I have been asked to take over the DNS/Sendmail services at my company and
in looking over the system I noticed several messages in the logs that look
like the following:

named[85]: [].53 attempted update to auth zone "vie.com"

Because the IPs are all from the root DNS servers and the db.cache was out
of date, I updated it with the most current and restarted in.named. A day
later and I am still receiving the errors. Everything looks to be correct
when compared to my DNS and Bind manual. Is this a normal message or any
ideas what might be wrong? We are running SunOS 4.1.3 with the native BIND.
