Performance statistics empty: data overflow

Does anyone have any ideas about "Performance statistics empty: data overflow" ?

From our alert logs:

Thu Jan 10 19:53:28 2002

This is alerted becuase one of the MTS stats has overflowed, the error report is a bug (1246206).

It means your statistics are incorrect but if you re-analyze the schema the message should go.
