Yes, I would think that would indicate two different mount points as well... Although there are multiple NFS mount points; _nothing_ else is happening on the machine; so I don't know where the other request is coming from. But - I will verify this by removing all the other NFS mount points and seeing if the problem "goes away." Then, we'll have a clear picture... - Dave Rivers -home | help
