This looks like a case of a reference to an object that's not in the
database.

Well, that's not helpful. :(  I'm disappointed there's no traceback.  Back
then ZEO tried to be more "clever" about logging.

Perhaps on the secondary, hack ZEO.StorageServer.ZEOStorage._pack_impl to
look like:

    def _pack_impl(self, time):
        self.log("pack(time=%s) started..." % repr(time))
        try:
            self.storage.pack(time, referencesf)
        except:
            logging.getLogger(__name__).exception("pack failed")
            raise
        self.log("pack(time=%s) complete" % repr(time))
        # Broadcast new size statistics
        self.server.invalidate(0, self.storage_id, None,
                               (), self.get_size_info())

And restart and try packing again.
