    ****************************************************************
    When multiple server regions are running and attempting to
    acquire an outbound IIOP connection there is a small timing
    window where IIOP outbound chain creation may occur multiple
    times resulting in duplicate chains.
    

Problem conclusion

  • Removed the timing window.
