``recursing``
This command dumps the list of queries ``named`` is currently recursing on, and the
list of domains to which iterative queries are currently being sent.
The second list includes the number of fetches currently active for
the given domain, and how many have been passed or dropped because of
the ``fetches-per-zone`` option.
This command dumps the list of queries ``named`` is currently
recursing on, and the list of domains to which iterative queries
are currently being sent.
The first list includes all unique clients that are waiting for
recursion to complete, including the query that is awaiting a
response and the timestamp (seconds since the Unix epoch) of
when named started processing this client query.
The second list comprises of domains for which there are active
(or recently active) fetches in progress. It reports the number
of active fetches for each domain and the number of queries that
have been passed (allowed) or dropped (spilled) as a result of
the ``fetches-per-zone`` limit. (Note: these counters are not
cumulative over time; whenever the number of active fetches for
a domain drops to zero, the counter for that domain is deleted,
and the next time a fetch is sent to that domain, it is recreated
with the counters set to zero).
``refresh`` *zone* [*class* [*view*]]
This command schedules zone maintenance for the given zone.
