Thanks GilaMonster, I´m aware about the nolock situation, and I know that removing that will solve that particular error. The thing is that the entire process (about 80 DTS) has that hint for about 5 years and never had problem. Actually is not a transactional database, so I could remove it, but the strange thing is why happend if there is no data movement at all.
I would understand it if someone insert o delete a lot of data, but nothing is happend on database at that moment! 🙁
We will check for IO problems...
