Error description
An extended delay with queue manager shutdown may be observed when using the pre-emptive (-p) option for the endmqm command. This is the result of WMQ internal monitoring. WMQ will check for the restartable MQ processes and restart any not found to be active. WMQ trace shows that during a pre-emptive end, the monitoring process doesn't take into account the current queue manager status (ending) and repeatedly restarts the missing WMQ processes. This results in a delay reaching an ended state.

Problem summary
**************************************************************** USERS AFFECTED: You may be impacted by this problem if you are using the pre-emptive (-p) option for the endmqm command. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: A restartable process such as the amqfqpub process may be repeatedly restarted by the queue manager during an endmqm -p shutdown. Each time, the restartable process ends because it detects that the qmgr is ending; and each time, the queue manager restarts it because it is missing. This cycle may repeat many times, until the queue manager has completed other shutdown work.
Problem conclusion
The problem has been eliminated by not allowing restartable processes to be restarted during queue manager shutdown. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.1 Platform Fix Pack 7.1.0.5 -------- -------------------- Windows 7.1.0.5 AIX 7.1.0.5 HP-UX (Itanium) 7.1.0.5 Solaris (SPARC) 7.1.0.5 Solaris (x86-64) 7.1.0.5 iSeries 7.1.0.5 Linux (x86) 7.1.0.5 Linux (x86-64) 7.1.0.5 Linux (zSeries) 7.1.0.5 Linux (Power) 7.1.0.5 Version Maintenance Level v7.5 7.5.0.3 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 ---------------------------------------------------------------
