Error description
Customer uses RequestDispatcher to dispatch a request.  After

occurs after some time.  The problem goes away for awhile if the
application server is restarted.

****************************************************************

PQ89799 introduced logic to reduce the number of Web Container
internally-initiated flush() calls in order to reduce chatter
between the Controller and Servant regions. However, if a
servlet uses an OutputStream rather than a Writer then the final
required automatic flush will not occur with 
PQ89799 applied.
This applies to WebSphere Application Server V5.0 for z/OS
only.
Problem conclusion
The Web Container in WebSphere Application Server V5.0 for z/OS
has been changed to cause the final automatic required flush to
be driven.

APAR PQ95568 is associated with SERVICE LEVEL W502017 of
WebSphere Application Server V5.0 for z/OS.
