Having sent my snarky "update" e-mail, I now ask... you say later in the mail that you are doing about 20 queries per second (which I agree should be handled by any hardware with more oomph than a Z-80).

I'm curious as to what these "200-500 legitimate connections" are.  Are they TCP?  If so, are you seeing lots of TCP connections hanging around?  Do you have some firewall in the midst of this that might be messing around with TCP connections?

If you do a "rndc recursing", what do you get?

If you are only doing 20-30 transactions per second, the stats on the UDP counts would have taken a long time to get there... something doesn't add up.
