Patch Name:  PHKL_1399

Patch Description: Fixes diskless client hang.

   This patch fixes a problem where diskless clients will work well
   for some period of time, (3 days in the case where the problem
   was found) and then freeze up.  This problem can be identified
   using adb or monitor.

   When the clients start to freeze up:
        try one of the following methods:

        adb:
                type the following command as root:
                        adb /hp-ux /dev/kmem
                Then type:
                        proto_stats+6/d
                wait 30 seconds and type
                        proto_stats+6/d
                again.  If the number is increasing at a rate of
                more than 1 per every 5 seconds then this patch is indicated.

        monitor:
                If the PROTOCOL STATUS screen of monitor shows that the
                number of requests dropped due to LACK OF FSPAGE is climbing
                steadily, then this patch is also indicated.

   This is only a problem if the server is an s700 running HP-UX 8.07.
   The clients can be S300 series running HP-UX 8.0 or S700 series
   running HP-UX 8.07.  This patch should be applied to any HP-UX 8.07
   diskless machine that is a diskless server or has a locally mounted
   file system.

   This defect is fixed in HP-UX 9.0.

   The file fixed was dux/netbuf.o

After getting the patch onto your machine, unshar the patch (sh PHKL_1399).

To install this patch do the following:
1) Run /etc/update (Note: you must be logged in as root to update
   a system).
2) Once in the update "Main Menu" move the highlighted line to "Change
   Source or Destination ->" and press "Return" or "Select Item".
3) Make sure the highlighted item in the "Change Source or Destination"
   window is "From Tape Device to Local System ...", then press "Return" or
   "Select Item".
4) You should now be in the "From Tape Device to Local System" window.
   Change the "Source:  /dev/rmt/0m" to "Source: /tmp/PHKL_1399.updt"
   (this assumes that you are in the /tmp directory where PHKL_1399.updt
   has been placed).  Note: You must enter the complete path name.
5) Press "Done".
6) From here on follow the standard directions for update.

The customized script that update runs will move the original software
to /system/PHKL_1399/orig.  HP recommends keeping this software there in
order to recover from any potential problems.  It is also recommended that
you move the PHKL_1399.text file to /system/PHKL_1399 to be retained for
future reference.

If you wish to put this patch on a magnetic tape and update from the tape
drive, dd a copy of the patch to the tape drive.  As an example the
following will create a copy of the patch that update can read:
dd if=PHKL_1399.updt of=/dev/rmt/0m bs=2048
