DNS & BIND Messages Log for XX+

[rengland]

The following is a sample of the /var/adm/messages, I have two server setup
in our internal environment that act as the (internal root) servers, we have
internal DNS server that our clients and server point to. These DNS servers
point to the (internal root) server that are secondary for all internal DNS
zones. This way if the client DNS server don't know about another internal
zone the (internal root) servers will know.  Our client DNS server have
forward statements that point to the (internal root) servers and the
db.cache file only has the (internal root) DNS server in it. The (internal
root) DNS server have a db.cache file that has the Internet Root DNS server.

Both root DNS server are running BIND 8.2.2 p7.  The log information below
only appears on one of the internal root DNS server, but not on the other,
any ideas why?  We do not have any Logging directives in the named.conf
file.  I know the messages Indicates that our name server received a
recursive query (XX+) from ip address for the address of the domain name.
What I don't understand is :
1.  Why does this message only appear on one of the servers?
Everything appears to be working ok. Should I be doing something
differently?

Thanks for the help.
