Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Version 6.1, 7.0, and 8.0 users of   *
    *                  the IBM AIO(Asynchronous Input/Output)      *
    *                  library(libibmaio.so) on Linux.             *
    ****************************************************************
    * PROBLEM DESCRIPTION: A write will timeout instead of         *
    *                      ending when the remote side closes      *
    *                      the connection.                         *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The AIO library was not properly reading a flag when an error
    condition was met. This resulted in the AIO library not
    properly reporting an error on the connection. When the error
    is not reported the connection will timeout instead of ending
    immediately.
