    * USERS AFFECTED: All Tivoli NPM V2R7 users.                   *
    ****************************************************************
    * PROBLEM DESCRIPTION: When using TCP/IP sockets for           *
    *                      communication and a null or oversized   *
    *                      TCP/IP buffer is received, an           *
    *                      ABENDU0006-08 may occur in FNMBUF10.    *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When a null buffer is received a flag is set to indicate this
    in FNMTCP10. Later FNMTCP10 frees the buffer using one variable
    and clears that variable. Then even later because the null
    buffer flag is set it tries to free the buffer again. But it
    uses a different variable whose value was set equal to the first
    variable when the buffer was gotten. This is what caused the
    NPM user abend U0006-08 in FNMBUF10.
    

Problem conclusion

  • FNMTCP10 is being changed to use a single variable to hold the
    address of the gotten TCP buffer storage.
