Thanks Andreas,

I was able to kill one of the Zope processes but not
pid 945. Maybe it wasn't a good idea, but even 'kill
-s HUP 945' had no effect. Zope is not running. Here
is what I get using 'zopectl fg' :

geneva# /usr/local/www/Zope/zope01/bin/zopectl fg
export EVENT_LOG_FILE
EVENT_LOG_FILE=
/usr/local/www/Zope/zope01/bin/runzope

line 198, in setupServers
    raise ZConfig.ConfigurationError(socket_err
ZConfig.ConfigurationError: There was a problem
starting a server of type "HTTPServer". This may mean
that your user does not have permission to bind to the
port which the server is trying to use or the port may
already be in use by another application. (Address
already in use)

Same exact error trying to restart Zope with
bin/runzope

As I mentioned, I can't even reboot the machine, the
shutdown command can't kill this process either.
