APAR Error Description / Circumvention

-------------------------------------------------
After the remote side of a connection closes and the local
socket issues a send that fails with errno value of EPIPE,
receives fail with errno value of ECONNRESET even if there is
valid data queued.

CORRECTION FOR APAR 'MA49559' :
-------------------------------
The receive code path was updated so that any valid data queued
on the socket is returned after the remote side is reset. After
all data is received from the socket, the next receive fails
with errno value of ECONNRESET. Additional receives after that
point get a return code of 0 indicating end of file.

CIRCUMVENTION FOR APAR 'MA49559' :
----------------------------------
None.
