Stuck on old script, can't rewrite, can't remove

[Ben]

I have a script that initializes a node.js web server, I'll call it /etc/init/myserver.conf. At some point tweaking the script, something broke and it started hanging. I've since stripped the script file down to the bare minimum, deleted the script file, run `initctl reload-configuration`, killed all the related processes, and nothing allows the service to be started or stopped again without hanging. Running `start myserver` or `stop myserver` hangs, and `status myserver` says "start/killed" or "stop/killed" depending on whether I just tried to run start or stop.

If I copy the contents of the file - cat myserver.conf > myserver_new.conf, and then `start myserver_new`, it works fine! But the exact same script with the old filename doesn't work.

How do I resolve this?
Thank you
