Problem summary

  • ****************************************************************
    * USERS AFFECTED:  Applications invoking AJAX services in      *
    *                  BPM.                                        *
    ****************************************************************
    * PROBLEM DESCRIPTION: When high volume of AJAX services are   *
    *                      invoked,                                *
    *                      ConcurrentModificationException may     *
    *                      occur.                                  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    During runtime if a heavy volume of AJAX services are loaded
    in coach, a ConcurrentModificationException may occur. The
    exception is intermittent and only happens when a large number
    of invocations happen.  This may cause some of the data to not
    load correctly.
    

Problem conclusion

  • The code has been modified to properly handle the accessing of
    objects during heavy load.  An interim-fix is available on
    v8.0.1.0 and has been integrated into the v8.0.1.1 fixpack.
    

Temporary fix
