Error description

  • uow_log_space_used - Unit of work log space used monitor element
    - might report incorrect amount number of bytes.
    In fact you might observe that the figures might go backwards if
    it is called multiple times.
    
    The original intent of the element was to report all the log
    space required for the current uow which would include both the
    log bytes written as well as any space reserved to support a
    rollback by the uow. However, the current implementation
    apparently only reports the "reserved space" and not the "actual
    number of log bytes written" within the uow.
