Show what task ansible was currently working on when I press Control-C?

I have an ansible (v2.9.6) playbook with lots of hosts. For some reason, something in my playbook is hanging, or at least taking a very very long time to finish (like 30 minutes). So I press Cntrl-C to stop it.

Even with -vvv all ansible tells me is [ERROR]: User interrupted execution. I am unable to find out what it was "executing", what it was waiting on, when I pressed Cntrl-C.

Is there anyway to see what exactly it is 'hanging on'?

Instead of outright killing Ansible with Ctrl/C, try sending it to the background with Ctrl/Z and then inspecting its process tree with ps f (or your own favorite ps options) to see what it is doing.
