Clean checkdb & checkcatalog - why is "Attempt to repair any minor problems" kicking in ?

A client was complaining that their DB Maint. plans ( on a server set
up by them )started failing.
Checked it out and once I turned the "Attempt to repair any minor
problems" off it was OK. I understand this is a known problem.
I never turn this option on myself so I am not familiar with it.
Integrity check should be running an DBCC CHECKDB, right?
So this option would probably be the equivalent of the REPAIR_FAST
option.
I did a dbcc checkdb and checkcatalog manually and both were clean.
Why is "auto repair" kicking in if everything is OK?
or
If there is a problem to fix why is it not showing up in DBCC?
Any suggestions?
Thanks
ZSeems like you assume that maint wiz first run DBCC CHECKDB without the repair option and if it find
a problem, it run again, using FAST_REPAIR. It doesn't. It just runs the command once, using the
FAST_REPAIR option. IMO, exposing this option in a wizard-like tool is bad design...

The command has to run in single_user mode and the maintenance job is
failing because of that. You shouldn't use that option and I've ensured its
been removed in SQL Server 2005.

Indeed. Thanks for catching that.
