Those yellow lights sure give a person a sick feeling, don't they?

In my previous place of employment we had a user written query/400
query that joined every record in a 500,000 record file with every
record in a 5 or 6 million record file and submit it to batch.  It
took all day, but the query ate up all the storage, and when all us IT
guys got back from a well deserved afternoon of golf, it was dead.
Died just after the last user signed off at 5:00.  I spent most of the
evening with IBM trying to find out why my AS/400 had an attention
light, but no users had called us with system problems.

That user got a refresher course in how to join files in query, and a
very hard time from everyone in the company.  Especially IT.
