I don't use plonectl, (I guess it comes with the universal installer?),
but usually when this error message appears, it means that the
Zope/Plone instance is already running somewhere else or in the
background.

On a Unix system, you can find the process number of the running
instance with "ps aux | grep Zope" and then just kill it.
