I don't believe so.  Not entirely sure what "weird middleboxes" refers
to in this context though.  And by resolver are you referring to my
BIND9 server or the resolvers on the clients of that server?

I've added packet capturing to the debug collection so that I can see
what my BIND9 server is sending and receiving in the way of queries and
responses when this happens again.
