My questions are, what is at fault here?  Is it a BIND bug to expect

It all sounds really odd. In particular, if there is no recursive client triggering them, and no prefetch, where are these ANY/A queries on TTL expiry coming from?

Are you certain there isn't some client activity triggering them? Or glue fetching (wouldn't account for ANY though).

The fact that it's flip-flopping between ANY and A records suggests to me you've got two separate things going on, and the ANY path is the problematic one. Can you see if there are any ANY (har har) queries coming into the recursive at all for these names/zones and from where?
