Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty Profile                      *
    ****************************************************************
    * PROBLEM DESCRIPTION: A RST packet is sent on a connection if *
    *                      data is left in the OS TCP buffers.     *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When the HTTP Channel closes the connection after a request is
    complete there could be a few bytes left in the Operating System
    TCP buffers. If this happens the connection will be closed by
    the Operating System with a RST packet rather than a FIN
    packet.
    

Problem conclusion

  • A new custom property will have the HTTP Channel read until it
    is told there is no more data when it's going to close the
    connection.
    
    The new custom property is:
    
    PurgeDataDuringClose
    
    The possible values are: true/false (default: false)
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 8.5.5.9.  Please refer to the Recommended Updates page for
