I can't replicate this at all. I am able to start and stop it with systemctl and /etc/init.d/
Here's what I see:
I'm not really sure what to do at this point. I'm considering doing a good old kill -KILL <pid>, but at the same time, I am not sure that's a good idea.
Update: I decided to give it a shot and used `kill` as I mentioned above. It worked.
