Hello,
After a upgrade from powerdns-recursor-3.7.3-3 to
powerdns-recursor-4.0.3-1 it does not return any dns queries anymore.
In the daemon.log is logged:
Oct 23 10:50:18 gateway001 pdns_recursor[3008]: Oct 23 10:50:18
Sending SERVFAIL to 10.3.3.134 during resolve of 'google.nl' because:

After a downgrade of powerdns-recursor-4.0.3-1 to 3.7.3-3 it is
working again, without making changes to /etc/powerdns/recursor.conf.
The customized configuration options in /etc/powerdns/recursor.conf:

Looks like your not getting out to the root name servers and/or their
delegations. I find it odd that you are claiming both authority for the
root zone and providing a hint file as well. I wonder if it's
reasonable to claim authority for the root zone, since they may change
it dynamically if there are problems with one of the name servers. I
think I would stay with just the hint file, though. Are you doing this
for security reasons? You could increase the log level and I believe
you will see the lookup chain and where it is failing. You could also
watch with tcpdump.

Do I need something to change to make it working against 4.0.x?
I've searched at powerdns.com to options that have changed in the
configuration but nothing helped.
Kind regards,

I have removed as suggested the auth-zones and hint-file declarations
and now the 4.0.3-1 is working. The tcpdump did show me that it could
not retrieve dns information from the root servers.
I don't know why I added this in the past but they aren't needed anymore
for my configuration.
Thanks
