Quick question I hope, we utilize unbound for our internal DNS (not having
used it before this place, I’m warming up to how awesome it is).

My question is, if we are doing between 95-127million queries a minute,
with 98.816% coming from the cache. Is it conceivable that running
unbound-control dump_cache could cause a 5 or so second pause in responses
as the cache is dumped to stdout?

Thank you for any insight!
