For me, this is where it gets stuck:

------
2017-05-16 19:12:53 sending all processes the TERM signal
2017-05-16 19:12:58 waiting for process termination (processes left: (1 494)) 
2017-05-16 19:13:00 waiting for process termination (processes left: (1 494)) 
2017-05-16 19:13:02 waiting for process termination (processes left: (1 494)) 
------

In my experience, it will wait here forever.

And from `ps aux`:
