Error description
You are running CICS TS 3.1 with webservice installed. There are 20 running ports, but for only one of these, you receive hundreds of messages per day indicating: DFHWB0153 x.x.x.x,PORTyyyy,The web asynchronous socket receive failed with an IO error. An exception trace point is issued, WB 0906, the socket is closed, and the request is terminated. . Gathering a dump triggered on the message DFHWB0153, there is an earlier exception trace point: SO 0E03 SOUS *EXC* - ASYNCIO_REQUESTED_FUNCTION_ERROR RETURN_VALUE(-1) RETURN_CODE(1120) REASON_CODE(00000000) The return and reason codes of the trace point indicate ECONNABORTED. Additional Keywords: MSGDFHWB0153 0B05 NOTIFY_ERROR BPX1AIO AIO#RECV KIXREVSCB

Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users * **************************************************************** * PROBLEM DESCRIPTION: Many DFHWB0153 messages are issued, * * and socket closed after webservice * * client sends ECONNABORTED. * **************************************************************** * RECOMMENDATION: * **************************************************************** There is an outstanding asynchronous RECEIVE for an HTTP TCPIPSERVICE. The RECEIVE completes with an error return ECONNABORTED and CSOL drives socket notify processing. This does not have code to handle the ECONNABORTED return code and therefore issues msgDFHWB0153. An ECONNABORTED during ASYNCIO can be caused by the client disconnecting. This condition does not require a message.
Problem conclusion
DFHSOS23 has been altered so that an ECONNABORTED returned from an ASYNCIO call will not result in message DFHWB0153.
