Error description
CSOL stops issuing ACCEPT to TCPIP once a non-zero return code is received from TCP/IP on the ACCEPT. This APAR is similar to PK47844 and PK51049 on z/OS. Additional Symptom(s) Search Keyword(s): KIXREVSCB MAXSOCKETs JRMAXSOCKETS TCP IP

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: The ACCEPT call for a TCPIPSERVICE * * fails and is not re-issued by CICS. * **************************************************************** * RECOMMENDATION: * **************************************************************** The CICS TCPIP listener task (CSOL) processes incoming connections via an outstanding ACCEPT. After processing the connection it issues another ACCEPT waiting for more work. This ACCEPT fails leaving the listener task unable to accept further connections for this TCPIPSERVICE. A CEMT INQUIRE TCPIPSERVICE will show that the TCPIPSERVICE is open, but user requests will not be processed until the TCPIPSERVICE is closed and re-opened. Please note that the same symptom will occur if TCP/IP does not issue a POST for the ACCEPT after ABORT processing that may result from a browser RESET. TCP/IP may need to be restarted in this case to enable the TCPIPSERVICE to function correctly.
Problem conclusion
DFHSOCK has been amended to issue a new message, DFHSO0130, and deregister the TCPIPSERVICE, when a non-zero return code is passed back from a BPX1AIO ACCEPT call. The CICS Transaction Server for VSE/ESA V1.1 Messages and Codes GC34-5561-08 will be updated to include the new message DFHSO0130 inserted at page 338 after message DFHSO0129A as follows: DFHSO0130 DATE TIME APPLID A TCPIP ACCEPT call has failed. The TCPIPSERVICE TCPIPSERVICE on port PORTNUMBER , at IP address IPADDRESS will be closed. The values returned are bpx_return_value( BPX RETURN VALUE ), bpx_return_code( BPX_RETURN_CODE ), and bpx_reason_code( BPX_REASON_CODE ). EXPLANATION: A TCP/IP ACCEPT call has returned an error. SYSTEM ACTION: An exception trace entry is made in the trace table. No system dump is taken, unless you have specifically requested a dump in the dump table. CICS continues unless you have specified in the dump table that CICS should terminate. The TCPIPSERVICE tcpipservice on port portnumber at the specified IP address is shutdown. When this shutdown is complete message DFHSO0108 is issued. The return value, return code and reason code reported by TCP/IP are displayed to aid with diagnostics. USER RESPONSE: Determine the reason for the ACCEPT failure. The return code and reason code included in the message text are described in the z/OS UNIX System Services Messages and Codes manual under the asyncio (BPX1AIO) callable service description. Check the system console for any messages issued by TCP/IP and take the recovery action indicated. The TCPIPSERVICE tcpipservice is closed, and after the TCP/IP problem has been resolved, the closed TCPIPSERVICE should be reopened. DESTINATION: Console MODULE: DFHSOCK XMEOUT Parameters: date, time, applid, tcpipservice, portnumber, ipaddress, bpx return value, bpx_return_code, bpx_reason_code
