The fact that "ocapi.py" is in "/usr/sbin" suggests that it's designed to be run as a script and not as a twistd plugin.  The shell script that you're citing is mostly irrelevant - that's just a wrapper to get twistd to run on your platform.

And, indeed, when I look at ocapi.py, I can see it has a 'reactor.run()' at the bottom of it, which means it's trying to run itself, not be run by twistd.  That's not how a file passed to '--python' is supposed to work.

Are you the maintainer of ocapi.py? If not, you'll have to get them to make some changes.
