I have seen this tried on an extremely busy database. It took almost 1.5hrs to get the database to a point where it would "suspend" blocking ALL processing while it goes into suspend mode. Once the BCV was "split", it was set to resume. If yours is an online/web backend - this could be a MAJOR problem.
