Ansible trava ao copiar de um host remoto para hosts remotos

Question

Eu queria copiar um arquivo gerado no hostA para servidores de produção e tentei a tarefa abaixo, mas o Ansible trava. Eu defino ssh_args=-i ForwardAgent=yes como é sugerido no post anterior mas isso não tem efeito. Qual é o problema aqui?

- name: Copy certificate from hostA to production servers                     
  synchronize:                                                   
    mode: pull                                             
    src: /etc/td-agent/ca_cert.pem
    dest: /etc/td-agent/ca_cert.pem                               
  delegate_to: "{{item}}"
  with_items: groups.production

UPDATE: o log é o seguinte:
