If so, problems are to be expected : there was a thread on the subject on -Stable and one outcome was the recommendation to use rather UDP with NFS v3 (NFS on TCP may be better on FreeBSD v4.0-Current, but -Current should not be used for production servers - more explanations on this subject via a post by Daniel C.
