$HOME/.ansible/tmp not cleaned up

Hello,

I use ansible 2.1.2.0
When running a playbook , the $HOME/.ansible/tmp temporary files are not cleaned up on the remote server, , a copy file is created and not deleted.

Do you know why ?
We have 3Go a temporary ansible files created in the $HOME directory of the user !!!

Regards

I have in the same way some files on the remote $HOME/.ansible.async directory that are not removed

I did create a ticket: https://github.com/ansible/ansible/issues/20128
