[Setup] Cannot start zeocluster for Plone 2.5.2

[James Biggs]

I'm new to plone, although I tinkered a bit in 2.5.1. I just installed 2.5.2 on
a machine running Ubuntu Server Edition, but when I try to start the zeocluster,
the ZEO server will not start.

I ran "bin/zopectl fg" and received the below output. Anybody know what may be
causing this? I cannot see how it is a port problem, since I could access my
plone site and zope manager in my previous installation of 2.5.1., which I just
updated today.
