Forum OpenACS Q&A: Re: upgrade (was: having problems. Refrain from using it until Sept 25th)

A close examination of the "ids to delete" query reveals that sent_date is *not null* for all rows in notification_user_map, which means that the outer joins are kicking in.  That is, there are rows in the notification/notification_request join that have are not matched in notification_user_map.

So the next step is to figure out why this is so.
