> >Thanks, that's a big help, we'll work on it. I updated the code from cvs just now(with tag RHEL4), and rebuilded it, and I got the same result. I did as follows: .mount GFS .start NFS service .mount NFS client .concurrently read from NFS .umount NFS client .stop NFS service .umount GFS Then I blocked there. I got the message "Stale NFS file handle" again. the process status of "umount" was "R+".
