If you physically turn off the server as opposed to just killing the nfsd processes, then it takes a bit longer than for the networking layer to time out the sock_release etc (isn't that under the control of the tcp_fin_timeout sysctl?), but AFAICS it does eventually get there. Are there any other details you're omitting? Cheers, Trond
