Playbook freezes at "getting output with communicate()"

[Ahmed]

Hello,

I'm using Ansible to manage configuration of a device that has a similar terminal to Cisco devices, The below playbook works fine but for every 4 or 5 times it freezes at sometimes.

I use Ansible-Debug=1, when the playbook freezes, it does at this line:

3385 1471938419.90376: getting output with communicate()

Playbook:

---

- hosts: all

  connection: local

  gather_facts: False

  no_log: True

  tasks:

  - name: test

    ignore_errors: True

    ios_command:

     provider:

      host: 10.10.10.1

      username: wasp

      password: wasp

      auth_pass: wasp

     authorize: yes

     commands:

      - show clock

Any idea what's happening?
