Steve suggested:
You could remove the adaptor Product from Zope the Zope Products folder and restart, the object will be broken, but deletable, then restore the Product and restart Zope.
Good Idea! That's about as simple as this sort of thing can get, I suspect.
Has anyone found a good way to delete a Database Connection that hangs Zope at startup? The connection seems to be waiting "forever", and so there is no access to the Zope interface, so of course I can't delete, or disable the offending object.
If there were just a way to set it to not connect immediately, prior to startup, that should be sufficient. The general question is, "How do you access a Zope Object, without running Zope?"
I was finally motivated enough to fire up Ty Sarna's Tranalyzer ( http://www.zope.org/Members/tsarna/Tranalyzer ) which makes it quite painless to find a point at which to truncate (the last few records of) the /var/data.fs file. Thanks! Jerry S.
