Although you have mentioned server 83.255.255.1, I actually have an IP block on 83.255.224.0/24 (perhaps 255.1 uses?). When I enabled the DNS queries, several servers in this block were hammering clrghouz - 10+ queries a second, and to the same records (so not honouring the TTL).

The TTL (negative) cache time might actually be my problem - I may not be returning the right response for an NXDOMAIN, its something I need to double check on to be sure (I think I need to included an SOA record in the authority record of the response), which I'm not doing.

I'll disabled that block for now - let me know if it works for you.
