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
