                               12DEC96


PROBLEM DESCRIPTION:

  An outage in TANDEM NSK TCPIP can happen if a user from another

  at the following World Wide Web location:

   http://www.sophist.demon.co.uk/ping/index.html


   For D30 and D40 versions, TCPIP will go into some tight
   loops. For D20 TCPIP, it could lead to a cpu halt.

   Releases affected: All


FIX DESCRIPTION:

   The following class C IPMs are available to fix this
   problem:

   T9551ACX for D30.

   No IPM has been planned for D20 TCPIP as D20 is at its end of
   life.
