In my case, I couldn't import DemoPortal.zexp or Wizard.zexp from PTK because oid 1377 was already in use. The pickle dump that followed contained references to ZDiscussions, which I had deleted some time before. After deleting the offending products and their directories, restarting zope, and packing, I ran tranalyzer -r on my problem Data.fs. I found that the problem oid was in this transaction: "/Control_Panel/Products/manage_importObject import into /var/lib/zope/var/Data.fs from /var/lib/zope/import/ZDiscussions.zexp" referred to by this transaction: "Installed product DemoPortal" in turn, referred to by this tranaction: "Added Globals" I think ZODB corruption when I see a record in one product refer to a record in an independent product and when the transaction of a deleted product doesn't go away.

This is very unlikely. What makes you think this?
