You might see occasional and temporary CPU usage increases when named.conf file is unusually large.
When a zone file is updated, a downstream effect is the ZoneRunner process to parse again the named.conf file. The parsing of an unusually large file may cause a temporary increase in CPU usage.
Unusually large named.conf file and zones are checked for updates (when the SOA expires).
None.
ZoneRunner does not issue a reload command when zones are checked for updates, so no CPU usage increases occur.
