ERROR: run_once is not a legal parameter in an Ansible task or handler

[Paul Morrison]

Hi,

run_once is still not working for me

ansible --version

ansible 1.7

Enter code here...---

- name: Freeze zones

  command: rndc freeze

  run_once: true

  delegate_to: "IXPDNS01"

  

- name: Thaw zones

  command: rndc thaw

  run_once: true  

  delegate_to: "IXPDNS01"

any ideas,

Paul Morrison
