DFHSO0102 date time applid A UNIX System Services Assembler Callable Service error (code X'code') has occurred on receipt of a severe TCP/IP return code; the TCPIPSERVICE tcpipservice on port portnumber at IP address ipaddress will be closed.

Explanation

An error has been detected in DFHSOLS. The error has been caused by a severe return code received from TCP/IP.

System action

An exception entry X'code' 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 will be shutdown. When this is complete then message DFHSO0108 will be issued. Message DFHME0116, which contains the symptom string for this problem, is produced.

User response

This error could have been returned if TCP/IP had been shutdown, for example. The exception trace entry will tell you which service routine was called and the return values that were returned. Refer to the z/OS UNIX System Services Messages and Codes book to determine the cause of the error.

The TCPIPSERVICE tcpipservice will be closed, and after the TCP/IP region has been restarted the closed TCPIPSERVICE should be reopened. At this point normal work can resume on the TCPIPSERVICE.
