SYMPTOMS

The DBCC CHECKDB command may cause an access violation (AV) to occur when you delete a text column with more than one page (8 KB) of text data while DBCC CHECKDB simultaneously checks the text column of that table.

CAUSE

DBCC CHECKDB does not correctly handle all conditions where SQL Server concurrently updates a TEXTPTR to null (which is what occurs when you delete text in a column).
