default paths:
  named configuration:  /etc/named/named.conf
  rndc configuration:   /etc/named/rndc.conf
  DNSSEC root key:      /etc/named/bind.keys
  nsupdate session key: /var/run/named/session.key
  named PID file:       /var/run/named/named.pid
  named lock file:      /var/run/named/named.lock

Steps to reproduce

  1. Set up a BIND server with at least one zone (master, slave, doesn't matter)
  2. Set minimal-any to yes in named.conf
  3. Start the name server
  4. Query this name server for zone/ANY over UDP

What is the current bug behavior?

BIND returns all the records at the queried name

What is the expected correct behavior?

I expect BIND to return only one RRset
