Hi,
I'm trying to understand the difference between clients-per-query
max-clients-per-query. I found a nice explanation by Mark Andrews here
[1] but then I wondered about max-clients-per-query.
Given a clients-per-query of 10, I assume that named will only queue
up 10 clients before it starts

If you set clients-per-query to 10 and max-clients-per-query to 100
(i.e., the default values), that means that the initial limit will be
10, but if we ever actually hit

3000 devices isn't much, even for a modest BIND server. Did this
configuration work in the past? What changed? Is there a network rate
limiting device in place that could be affecting the queries to the
authoritative servers? Have you talked to your networking team? They
