>I haven't read all of this thread so I don't know if this has been brought up already. It sounds like some of the objects within your data provider are hanging around a lot longer than you expect.

I have seen SQL Server hold a connection until the garbage collector disposes the object.

I am using VFP as the backend. Is there a way to enable an event log for that? Also, based on this, I am not sure exactly what I would have to do to verify for that.
