Error description
When performing a pre-emptive shutdown of the queue manager (endmqm -p), a failure data capture (FDC) file may be generated by the amqzmur0 process with probe ID ZX015050. This behaviour may be observed on queue managers running on the MQ Appliance or on distributed platforms. The contents of the FDC file are similar to the following: +--------------------------------------------------------------- --------------+ | | | WebSphere MQ First Failure Symptom Report | | ========================================= | | | | PIDS :- 5725-S14 | | LVLS :- 8.0.0.5 | | Vendor :- IBM | | O/S Registered :- 1 | | Data Path :- /var/mqm | | Installation Path :- /opt/mqm | | Installation Name :- MQAppliance (1) | | License Type :- Unknown | | Probe Id :- ZX015050 | | Application Name :- MQM | | Component :- zxcStopAgents | | SCCS Info :- /build/slot1/p800_P/src/lib/zu/amqzxmb0.c , | | Line Number :- 10994 | | Build Type :- IKAP - (Production) | | Program Name :- amqzxma0 | | Arguments :- -m QM2 -u mqsystem | | Addressing mode :- 64-bit | | Thread :- 1 ECMain | | UserApp :- FALSE | | Major Errorcode :- MQRC_Q_MGR_STOPPING | | Minor Errorcode :- OK | | Probe Type :- INCORROUT | | Probe Severity :- 4 | | Probe Description :- AMQ6125: An internal IBM MQ Appliance err or has | | occurred. | | FDCSequenceNumber :- 0 | | | +--------------------------------------------------------------- --------------+ MQM Function Stack amqzxma0 zxcExecutionController zxcStopAgents xcsFFST

Problem summary
**************************************************************** USERS AFFECTED: This is a very low impact problem and only affects customers that start and stop queue managers in very quick succession. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: The FDC indicates that one of MQ's internal tasks received MQRC_Q_MGR_STOPPING during initialisation, but there was no provision in the internal logic of the task to handle this reason code at this point. The task ended as a result of this issue but it had no impact because the queue manager was ending anyway. This APAR fixes a similar, but distinct, issue to that reported in IT15208
Problem conclusion
The affected internal tasks within the MQ queue manager have been updated to correctly handle the MQRC_Q_MGR_STOPPING reason code. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.6 v9.0 CD 9.0.2 v9.0 LTS 9.0.0.2 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
