[Zope] Strange Zope behavior/Instability (Zope going down)

[Rob Sporleder]

All of the python z2.py processes are still running. I haven't checked if I
can get to it using http://localhost. The server is offsite. However, I did
try an http get from the command line and it did not respond.

Wow. Ugly.  Are the Zope processes still up after you've lost connectivity?
 If so, can you get a browser on the machine running zope to access it?
http://localhost:8080, or whatever port your running on.
