Well, I was seeing the same thing with some of the zones. 
After I took them down, before the maintainer of the domain took my server 
out of the authoritative lists, my server got pounded with queries which 
also helped to kill it on some occasions.

I thought 2.9.8 was supposed to do recursion on its own?

A friend of mine runs BIND on my secondary name server, so I'll ask him if 
he can slave the two anti-spam zones. I was doing too - but 
NOT the DNSBL (, just the main zone.
