    Under high user loads it was possible that an HTTP request
    header could be corrupted.  In this instance, the 'Host' was
    incorrect.  It is also possible that the URL or any other
    data correlatable field might be corrupted.
    

Problem conclusion

  • A fix was applied so that data correlation is only allowed
    to run once per action.
    

Temporary fix
