Error description

When a JMS client application connects to Service Integration
Bus with wait, it times out and the following errors appear in
the client log:
CWSIA0067E: An exception was received during the call to the
method JmsMsgProducerImpl.<constructor>:
com.ibm.websphere.sib.exception.SIErrorException: CWSIJ0046E: An
internal error occurred..
at com.ibm.ws.sib.api.jms.impl.JmsMsgProducerImpl.<init>
                                (JmsMsgProducerImpl.java:481)

****************************************************************
A physical network connection to a messaging engine can host
many concurrent conversations (e.g. JMS sessions), each
performing their own operations (requests). Each of these
requests are allocated an ID while it is active. The IDs have
a maximum value, after which they wrap around and old IDs are
reused.

It is possible for an individual request to run for a long
time. Specifically, a synchronous receive with a long timeout,
when no messages are available.
If an individual request runs for long enough for the IDs to
wrap, there is a risk that its ID will be reused by
another conversation (on the same physical network connection)
whilst the original request is still active.

The code incorrectly deals with this situation by throwing a
CWSIJ0046E when an attempt to re-use an active request ID
occurs.

Problem conclusion

The fix for this APAR alters the code that allocates request
IDs to handle the situation where wrapping causes an attempt
to re-use an active request ID. The situation is detected and
handled (by allocating a different request ID) without any
exception being thrown to the application.

The fix for this APAR is currently targeted for inclusion in
fix pack 6.1.0.35 and 7.0.0.13.  Please refer to the
