PQ88891: Broker is over-sensitive to loss of the queue manager.

APAR status
Closed as unreproducible in next release.

Error description
JMS server gets abend 0c4 (ABENDU4088) at termination process
because dll module imbdfjps.lil was deleted in pthread_quiecs
process in its mother task.

It seems that the dll modules, imbdfmqm.lil and imbdfjps.lil in
the directory WebSphere/V5R0M0/MQSeries/pubsubroot/lil, were
incorrectly processed during the cleanup processing.

Looking at the SYSLOG it appears that the broker is stopped
before the queue manager is stopped.  But this is only the
shutdown timeout.  From the messages in the log it takes longer
than the prescribed time (currently about 5 secs) to shutdown.
The queue manager is then stopped, and it is this that appears
to cause the broker to fail.

The broker is over-sensitive to loss of the queue manager.
Local fix
Everything restarts without problems when the system is
recycled.

* RECOMMENDATION:                                              *
****************************************************************
The event broker process gets abend ABENDS0C4/ABEND0C4 at
termination. This happens when the queue manager stops before
event broker processes. This problem is in the shutdown path and
not during regular messaging processing.
Problem conclusion Temporary fix Comments
This problem is not reproducable in the future release of
WebSphere Application Server for z/OS. The reporting customer
has therefore allowed the issue to be closed as UR1.
