Error description

• Numerous DFHSO0106 Language Environment Callable Service Error
  (Code X'0236') has occurred in Module DFHSOCK messages are
  received.  Your CICS web service transactions stop working
  and you are required to re-cycle CICS and TCPIP.
  The trace entry shows the following exception:
  SO 0236 SOCK  *EXC* - GIVESOCKET_ERROR RETURN_VALUE(1)
                        RETURN_CODE(1124)
                        REASON_CODE(000000FF)
  .
  Backing up in the trace, you see the socket has been closed
  Return code 1124 RC1124 x'0464' means ENOTCONN indicating the
  socket is not connected.  Reason code 0FF RSNFF means
  JRStatusPosted - A request was received to dub a thread for a
  process that is stopped or has ended.
  This problem is similiar to APARs PQ67055 and PK56675,
  but issued for a different return code.  The error and the
  dump are too severe for this condition.  Code will be
  provided to handle this as a soft error and output an exception
  trace entry.

  ****************************************************************
  A new connection arrives in sockets domain because of an HTTP
  request from a browser. CSOL (the CICS sockets listener task)
  issues a GIVESOCKET ( BPX1GIV ) against the newly accepted
  socket.
  
  The GIVESOCKET return code ( AIORC ) is ENOTCONN ( 1124 ).
  This is returned by CSI TCP/IP because the connection with the
  browser is no longer there. This is a common response to
  GIVESOCKET requests but CICS issues a console message
  (DFHSO0106) and takes a system dump with dumpcode SO0002 in
  response to the error.

Problem conclusion

• DFHSOCK has been changed to avoid issuing message DFHSO0106
  and taking a system dump when a GIVESOCKET request fails
  with ENOTCONN.
