APAR Error Description / Circumvention

-----------------------------------------------
Socket receive APIs fail with errno ECONNRESET after both sides
of a connection shutdown.

CORRECTION FOR APAR MA49605 :
-----------------------------
The code path was updated so that socket receive APIs return
zero, indicating end of file, when a connection is shutdown
cleanly.  If a connection is unexpectedly reset by the remote
side, the receive API will still fail with errno set to
ECONNRESET.

CIRCUMVENTION FOR APAR MA49605 :
--------------------------------
None.
