unable to map global section

    Explanation: The defragmentation process could not map the system
    wide global section created by the scheduler. This error is
    very unlikely, but could be caused if the scheduler exits after
    creating the global section and the defragmentation process,
    but before the defragmentation process has a chance to map the
    global section. It will also occur if the user tries to run the
    DFG$ENGINE_MAIN program directly.

    User Action: None.
