APAR status

  • Closed as program error.

Error description

  • Each time the client process terminates we close down our
    socket connection.  Due to a bug in the code we would pass
    the contents of a piece of memory that was not actually
    where the file descriptor for the socket was stored to the
    close() function.  This would eventually cause the server
    daemon to stop sending routing information to client
    processes, resulting in 404s since those clients didn't know
    where to route the requests.

    ****************************************************************
    * PROBLEM DESCRIPTION: ODRLIB Client processes would return    *
    *                      404s after Daemon process stopped       *
    *                      sending routing updates                 *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The Daemon process would incorrectly corrupt it's state leading
    to the closure of the socket used to provide routing updates to
    Client processes
    

Problem conclusion

  • Replaced incorrect implementation of lists containing numeric
    values with the latest code that correct the defects in that
    implementation.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 9.0.0.11.  Please refer to the Recommended Updates page for
