I'd say it's probably just a matter of the fact that the system wasn't designed to handle zillions of failed transactions all at once.

Let me compare it to something online. Say, you have a simple forum system online, that has a couple of message boards on it. You want to move a bunch of posts from one board to another, because someone posted a bunch of off topic junk. But, you never installed a "move message" function, because everything was so small, you figured it'd be cake to handle it on a case-by-case basis, which was true, until you took a week off, and someone posted 500 messages in the wrong place.

Now, you either need to implement software to handle the task for you, or you need to go and edit the database manually to change 500 records.
