PH05242: DFHSO0130 A TCP/IP ACCEPT CALL HAS FAILED. TCPIPSERVICE WILL BE CLOSED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You are running CICS and receive the following message:
  DFHSO0130 REGNAME A TCP/IP ACCEPT call has failed.
  The TCPIPSERVICE HTTPNSSL on port 1111 at IP address
  ANY will be closed.  The values returned are
  bpx_return_value( -1 ), bpx_return_code( 120 ), and
  bpx_reason_code( 1,986,134,673 ).
  
  The codes mean the following.
  bpx_return_value( -1 )
  -1     Means there was an exception, check the retcode
         and rsncode.
  bpx_return_code( 120 )
  120    0078     EINTR   A function call is interrupted.
  
  bpx_reason_code( 1,986,134,673 )
  This means rsn 76620291
  TCPIP
  JrTcpError: Tcp returned an error identified by the
              return code
  
  Reason code qualifier 7662 indicates that the error
  represented by the reason code is not an OS/390 UNIX
  reason code. Reason code 0291 indicates a return code
  of JRTCPERROR with description, "TCP returned an error
  identified by the return code," which is the 120 errno
  from above.
  
  This APAR will change CICS so we can retry issuing the ACCEPT
  call when it fails with EINTR instead of closing the
  TCPIPSERVICE.

  * PROBLEM DESCRIPTION: Message DFHSO0130 is received with:     *
  *                      bpx_return_value( -1 ),                 *

  ****************************************************************
  When running CICS the following message is issued if an EINTR
  exception is encountered:
  
  DFHSO0130 applid A TCP/IP ACCEPT call has failed.
  The TCPIPSERVICE tcpipservice on port xxxx at IP address
  xxxx will be closed.  The values returned are
  bpx_return_value( -1 ), bpx_return_code( 120 ), and
  bpx_reason_code( 1,986,134,673 ).
  
  The TCPIPSERVICE is then closed.
  bpx_return_code (120) indicates an EINTR exception has occurred.
  For EINTR exceptions the Async Accept call should be retried.
  

Problem conclusion

• DFHSOLS has been changed to retry EINTR exceptions received
  during Async Accept Calls.
  The Accept call will be retried up to five times, if the call is
  unsuccessful after five attempts then continue to process the
  error.
