Forwarders being ignored

Recently I've been seeing some odd traffic from my DNS servers.
We are running a split/split DNS system and my internal DNS server consider
themselves to be root and authoritative for my domain. I've setup forwarders
to some external DNS servers I have with:
options {
directory "/var/named";
forwarders {
A.B.C.D; // Sanatized for security reasons
A.B.C.E;
};
};
My cache file lookes like:
; last update: Jan 21, 1995
. 99999999 IN NS host.domain.com.
host.domain.com. 99999999 IN A A.B.C.F ; Sanatized
Occasionaly I see my internal DNS servers sending queries directly
to nameservers rather than through the forwarders. I've looked over my
configuration and everything looks kosher, I can't even begin to understand
how my internal servers are getting the information to even send the query.
Can someone explain to me how what I'm seeing is possible and what
I might do to correct it?
Thanks
-Bob
