  * Clients issuing MQGET to get or browse a message receive     *
  * MQRC_NOT_CONVERTED (MQRC 2119) when the message contains     *
  * very large RFH2 headers.                                     *

  ****************************************************************
  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.
