APAR Error Description / Circumvention

-----------------------------------------------
System is unresponsive due to Streams unable to allocate new
Streams message. LICLOGs VL1F000009 (Stream I/O) are posted to
indicate Streams is unable to allocate new Streams message.

CORRECTION FOR APAR MA49055 :
-----------------------------
System TLS was leaking streams messages in a path when there was
application data to be sent after the socket has already been
told that the remote side has closed the connection.  This path
was updated so that the streams messages are no longer leaked.

CIRCUMVENTION FOR APAR MA49055 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


None.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
