Looking over a new SQL Server I noticed a failing job. It was the ‘Check DB’ part of a maintenance-plan and contained this error message …

Msg 2508, Level 16, State 3, Line 1
The In-row data RSVD page count for object “SomeTable”, index ID 0, partition ID 104586854531027, alloc unit ID 104586854531027 (type In-row data) is incorrect. Run DBCC UPDATEUSAGE.
CHECKDB found 0 allocation errors and 1 consistency errors in table ‘SomeTable’ (object ID 1595868725).

It transpired that this box was once upgraded from SQL-2000 and some steps had been missed.

It was trivial to fix (and not a sign of corruption) …

DBCC CHECKDB WITH DATA_PURITY;
GO
EXEC sp_MSForEachDB 'DBCC UPDATEUSAGE(?);';
