It doesnt matter if it is the first post, the last post or any post inbetween. As i said, it could be due to the backup script, it could have been due to an overflow of posts at that time. It could have just been vB acting like a idiot. We dont know exactly why the database errors come up when they do. We have looked into it and there is no full explanation as to why it happens. It just does. vB is of no help getting it resolved either.
