  • Disable ESIInvalidationMonitor property (set its value to false)
    in plugin-cfg.xml to bypass the problem.
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Plugin V7.0 and above.               *
    ****************************************************************
    * PROBLEM DESCRIPTION: The WebSphere HTTP Plugin could fail    *
    *                      to establish the ESI Monitor            *
    *                      connection.                             *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The HTTP Plugin will fail to establish the ESI Monitor
    connection, which is done when the ESIInvalidationMonitor is
    set to true in the plugin-cfg.xml, when it fails to remove the
    $WSRH private.  It will issue an error message and abort the
    attempt to create the connection until the next request.
    The $WSRH may not be set when running on the IBM HTTP Server
    on z/OS that is not based on the Apache server.
