Error description

• Use DB2 MQ function MQSEND to send a message with
  default configuration, a reply message will be seen in the
  queue. The default message type sent by MQSEND should be
  datagram, which doesn't need a reply, but because of a bug in
  the code, in fact it sends a request message instead, which
  needs a reply. From MQ AMI trace, the following information will
  be seen:
  
     ! MD report options 0x0
     ! MD message type 1
     ! MD expiry -1
     ! MD feedback 0x0
     ! MD encoding 0x222
     ! MD ccsid 0
  
  Message type 1 means it's a request type of message, refer to
  this link:
