No, never heard of this issue. You will have to post relevant code or a

I just read a kb article that gave me some hope but nothing, i was
checking the Stored Proc but it dont use any of the causes of this bug,
here is for someone :P who need it:

I'd try putting any of the ntext/text or image data types
at the end of your select clause.
