The same problem was encountered by Rick Hanlon II here: https://coderwall.com/p/4tcw7w
Option stopasgroup=true should be set in the program section for supervisord to stop not only the parent process but also the child processes.
The example is given as:
[program:some_django]
command=python manage.py runserver
directory=/dir/to/app
stopasgroup=true
Also, have in mind that you may have an older package of supervisord that does not have “stopasgroup” functionality.
I tried these Debian packages on Raspberry Pi:
- supervisor_3.0a8 does not work.
- supervisor_3.0b2-1 works as expected.
