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.
