Are you doing query logging on this box? If so, you might check for
messages such as:
named: clients-per-query decreased to 17
I know you tried setting max-clients-per-query earlier, but since this
is for a locally-hosted zone, query volume could be quite high
somewhere along the way. Likewise, you might run
and see what you get.
Something else you might try: if you don't already, turn on
You may get what you're looking for; you may not.
