Well, I hate to contradict GH, but at least here (SunOS 4.0.1) it's
still not fixed.  One of our three servers hangs about once a day
(a YP binding problem :-< ) and one of the 18 or so clients which
mount that server's partitions will start complaining about a "stale
NFS file handle".  I wish there was a way to fix this; sometimes
umount/mount will do it and sometimes only a reboot will do (the umount
hangs).  Curiously, it's almost always the same file system on
that server, perhaps because it is one of the most heavily used.
