[Pdns-users] Very odd negative cache behaviour for world-gen.g.aaplimg.com

[Matthias Cramer]

Hi Remi

I found out that when I set dnssec to false the it seams to work much better. Also setting minimum-ttl-override to 60 helps a lot, even When dnssec is enabled but only on 3 of 4
resolvers.

Can you give me a hint how I can get all the queries you are looking for logged?

Attached is a log which loglevel of 3 and quiet=no and a trace to the domain in question via "rec_control trace-regex 'world-gen\.g\.aaplimg\.com'"

Regards

  Matthias
