Hi,

I’m developing a “custom ansible module” to start a long running background process on the remote host.  
As per the response for the post [https://github.com/ansible/ansible/issues/28264](https://github.com/ansible/ansible/issues/28264), Ansible connection stays  
until all the processes are terminated.  
And that matches with the ansible generated code below.

p = subprocess.Popen([‘/usr/bin/python’, module], env=os.environ, shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE)  
(stdout, stderr) = p.communicate(json\_params)

p.communicate(json\_params) waits until all the processes (including child) are terminated.i

is there a way to do this ? async or systemd is not an option since my custom module is going to invoke another python script which will start the process.

Thanks in advance!!!

Regards,  
Senthil
