Does this mean you are using the "soft" mount option? Without that, I would expect access to the mount to hang until the network connection is restored, regardless of whether the TCP or UDP transport is used. The default retry and timeout behaviour *is* different between transports, though. See the "timeo" and "retrans" options in nfs(5). You may wish to override the defaults in your environment.
