Path Name:  /hp-ux_patches/s700/9.X/PHCO_5061

Symptoms:
        PHCO_5061:
        1.  Unable to umount a stale NFS mount.
        2.  "Device busy" error from umount.
        3.  The fuser program lists no users on an NFS mount, when
            in fact there are users on the mount.

Defect Description:
        PHCO_5061:
            The defect resolved by this patch is the inability to
            umount a stale NFS mount because of a "device busy"
            message (a stale NFS mount is an NFS mount to a machine
            that not accessable).  The specific message from umount
            is:
                 umount: umount(1M) of <device>: Device busy
            where <device> is a stale NFS mount.

            The "device busy" message indicates that open files
            exist on the stale mount.  An administrator needs to
            kill the processes with open files on the mount before
            proceeding, however, the 'fuser' command cannot list
            processes using files on an NFS mount.

            The 'sfuser' program provided in this patch can find,
            and kill processes with open files on an NFS mount.
