I setup my servers as slaves of the parent domain, and that seems to 
have fixed the problem so far.
It seems like a hack though.

Reading through other solutions to other problems posted to this list 
since I joined, I had the idea that maybe I should setup the parent 
domain servers as forwarders? but do I really want to push all internet 
lookups through those servers and add that additional hop?

Is there some better way to solve this problem?
