The options at the bottom (serial and forks) hangs the whole process if there’s one server that is waiting for user input for some random reason (change password, authenticity of host can’t be established as two examples)

Is there anyway to get past this hangup ?

i’ve tried ignore\_errors: true and ignore\_unreachable: true

Are these even needed ?  
(they are trials that seem to increase speed in running the ansible user management script against a 75 or so servers… )

- name: “Add or remove users”  
hosts: tag\_ansible\_managed\_true  
serial:
  - 10  
become: true  
gather\_facts: true  
strategy: free # noqa: run-once[play]  
roles:
  - amazon\_user\_accounts  
…

and in ansible.cfg  
forks=10
