Sorry, I haven't been following this thread, but I will note that I've seen (repeatably) in my test Zope environment this behaviour. This is probably unrelated though... For me, the situation comes about when I am loading up my fresh (ie. clean ZODB) test Zope with a thousand users. While the load script is running (it runs on the command-line and goes TTW using urllib to register the users) if I access a page which summarises all users, I *sometimes* get None for some of the users. The page uses a Catalog to find basic user info, and sometimes uses getObject() to find the real user object. The getObject() appears to return None sometimes. Once the load is complete, I don't see any errors. So I blame some mechanism failing under load. I also often see ReadConflictErrors, but I understand they're going away soon :) Richard
