I expect you'd get better advice on a Zope list, like


If it's an identifiable problem with ZODB/ZEO 3.4.1, then this (zodb-dev) is
a good place to discuss it, but since there are no other reports of this I
have to suspect it's due to a problem(s) in your specific Zope and/or Plone
configuration.  For example,

suggests OS-level permission problems (do you get log messages?  exceptions?
the process hangs?  ... "fails to start" could mean a lot of things).

You could try running test.py with the "--all" switch, and that will run
more ZEO connection tests.  Those are ZEO unit tests, though.  AFAIK, there
is nothing in the test suite that specifically tries to run Zope with ZEO.
