  • 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.
