* PROBLEM DESCRIPTION: Message-driven beans unable to          *
*                      process messages when multiple          *
*                      listener ports present                  *

* RECOMMENDATION:                                              *
****************************************************************
If an application server is configured with multiple listener
ports, it is possible that upon message-driven bean startup,
one or more of the message-driven beans do not process
messages.
This is caused by a timing problem at listener port start that
prevents server sessions from being used to process messages.
In a system that uses multiple servers to process the same
WebSphere MQ queue, the symptoms for this problem may include
message processing delay, as the messages are marked by the
queue manager for a period of time before being made available
to other application servers.

Problem conclusion

The timing problem has been resolved to ensure that server
sessions are available to process messages.
