    *                      BATCHLIM bytes have been transferred.   *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When messages are sent across a channel, and the number of bytes
    transmitted in the current batch exceeds the channel's BATCHLIM
    setting the batch should be closed, causing a confirm request to
    be sent to the remote channel, and any uncommitted messages to
    be committed. However, if the channel is using a large (>32K)
    transmission buffer (for example, when sending large messages)
    this does not occur correctly, and the batch is not closed until
    BATCHSZ messages have been sent or the transmission queue has
    been empty for more than BATCHINT seconds.
    

Problem conclusion

  • rriSendData is changed to correctly update the count of bytes in
    the current batch when using a large transmission buffer, so
    that the batch is correctly closed if the transmission of a
    message causes the number of bytes sent to exceed BATCHLIM.
