IT33028: An MQ client receives return code 2119 "MQRC_NOT_CONVERTED" fromMQGET when an RFH buffer exceeds the SSL transmission size limit

APAR status

• Closed as program error.

Error description

• An MQ Client attempted to MQGET an RFH2 packet whose size
  exceeded the SSL limit. When the limit was reached but data
  remained, internally an MQRC_HEADER_ERROR was returned for
  certain levels/hosts. The error was unnecessary as the rest of
  the packet would have been successfully delivered. RC 2119
  MQRC_NOT_CONVERTED was then returned to the application but the
  error should have been ignored in this case.
