Error description
The IBM MQ channel pooling process 'amqrmppa' is abruptly terminated. The following sequence of failure data capture (FDC) records is generated: First FDC: Probe Id :- ZS402099 Component :- zstAsyncConsume Program Name :- amqrmppa Major Errorcode :- MQRC_SYNCPOINT_NOT_AVAILABLE Arith1 :- 2072 (0x818) Arith2 :- 2072 (0x818) MQM Function Stack zstAsyncConsumeThread zstAsyncConsume xcsFFST Second FDC: The second FDC is generated when processing MQDISC and the MQM Function stack contains MQDISC. Example 1: Probe Id :- ZS013010 Component :- zsqVerifyPCD Program Name :- amqrmppa Thread :- 8013553 RemoteResponder Major Errorcode :- MQRC_HCONN_ERROR MQM Function Stack ccxResponder rrxResponder ccxReceiveThreadFn ccxReceiveThreadCleanup cciEndConv rriAsyncConvControl MQDISC zstMQDISC zifMQDISC zsqVerifyPCD xcsFFST Example 2: Probe Id :- ZC004062 Component :- zcpCreateMessage Program Name :- amqrmppa Thread :- 77410 RemoteResponder Major Errorcode :- STOP Probe Type :- HALT6109 MQM Function Stack ccxResponder rrxResponder ccxReceiveThreadFn ccxReceiveThreadCleanup cciEndConv rriAsyncConvControl MQDISC zstMQDISC ziiMQDISC ziiCreateIPCCMessage zcpCreateMessage xcsFFST The first FDC with error MQRC_SYNCPOINT_NOT_AVAILABLE indicates that the queue manager was not able to honor the sync-point request. The subsequent FDCs indicate error when processing MQDISC request followed by the amqrmppa process ending abruptly.
