  ****************************************************************
  After the client channel gets a message, rstSendAsyncMessage
  is called to send the message to the client. This routine
  segments the message based on the maximum transmission size for
  the channel (approx 32K for non-SSL channels/15K for SSL
  channels), and calls rriConvertValidate to convert the
  transmission to the client's encoding/ccsid, and validate the
  length of any headers in the message.
  If the message contains large RFH2 headers, causing the headers
  to span beyond the end of the first transmission segment,
  rriConvertValidate incorrectly determines that the header length
  is wrong, causing MQRC_NOT_CONVERTED to be returned.
  

Problem conclusion

• rriConvertValidate is changed to no longer set
  MQRC_NOT_CONVERTED in this situation.
