APAR Error Description / Circumvention

-----------------------------------------------
Source applications with secure DRDA connections which have been
lost may fail to reconnect when the Target system becomes
available again.

While the target system is unavailable, the source job will
generate repeated messages:

CPF9162 - Cannot establish DDM connection with remote system.

These failed SSL connection attempts are not calling
gsk_environment_close
So, the source job will eventually start to throw error message
CPD3E34:

From user . . . . . . . . . : QTCP
From module . . . . . . . . : QRWXDLL
From procedure . . . . . . : SndCPD3E3x__FiT1
Statement . . . . . . . . . : 23
To module . . . . . . . . . : QRWXDLL
To procedure . . . . . . . : SndCPD3E3x__FiT1
Statement . . . . . . . . . : 23
Thread . . . . : 00000105
Message . . . . : DDM TCP/IP communications error occurred on
gsk_environment_init - SSL.
Cause . . . . . : Error code (errno) 0 was received while
processing the
gsk_environment_init - SSL function for DRDA/DDM TCP/IP
communications.
Recovery . . . : See any previously listed message(s) to
determine the
cause of the error; if necessary, correct the error and issue
the request
again.

This is due to all 64 of the GSKit environment slots being
filled and returning GSK_INSUFFICIENT_STORAGE.

If the connect() fails, the gsk_environment_close() should be
issued by the application to clean up.

CORRECTION FOR APAR SE72190 :
-----------------------------
Calls to do gsk_environment_close() for connect() failure were
added.

CIRCUMVENTION FOR APAR SE72190 :
--------------------------------
None.
