even sending notifies by slaves can have a reason. for example, other
slaves not getting notifies from master...
Do you think if server needed to resolve something, and you would disable
it, it would work better? I think just the oposite. If a server does lookups
only when needed, then disabling required lookups would make it not working.
I think that if server is authoritative - and - slave-only it should
use system resolver rather than querying by itself.
BIND will not use system resolver. BIND is the resolver. Relying on
other resolver could cause troubles. If BIND does not need to resolve,
it will not. If it needs, don't block it.
Where can I find information about what causes queries for internal
duties? If it can be found in ARM, could you please point me to the
right chapter. May be I missed something while reading it. The only
mention I have met is that additional resolving is needed for sending
notifies (And will this resolving be performed in case of list of
slaves' ip addresses is written in named.conf?).
Someone other will have to answer this.
