Interesujące opcje dotyczące poprawy parametrów serwera min-retry-time oraz max-retry-time, których opis znajduje się w sekcji Tunning na stronie z dokumentacją serwera Named: Tuning (v9.9) | Tuning (v9.8.2)

min-refresh-time, max-refresh-time, min-retry-time, max-retry-time
These options control the server's behavior on refreshing a zone (querying for SOA changes) or retrying failed transfers. Usually the SOA values for the zone are used, but these values are set by the master, giving slave server administrators little control over their contents.

These options allow the administrator to set a minimum and maximum refresh and retry time either per-zone, per-view, or globally. These options are valid for slave and stub zones, and clamp the SOA refresh and retry times to the specified values.
