Ansible playbook freezes at getting output with communicate()

[Ahmed]

I'm using Ansible to auto configure a device that has an OS similar to Cisco IOS, the below playbook works fine but every 4 or 5 times I run it, it freezes, I'm setting ANSIBLE_DEBUG=1, when it freezes, it does at the following line:

3723 1472024022.64431: getting output with communicate()
