APAR status

  • Closed as program error.

Error description

  • A CICS task issues an EXEC CICS WEB RECEIVE or WEB CONVERSE
    command.  The task's profile specifies an RTIMOUT of NO which
    means that the program should wait indefinitely for a response
    from the remote server.  However CICS incorrectly sets a timeout
    of approximately 18 hours on the suspend (65535 seconds).

    ****************************************************************
    A CICS application issuing an EXEC CICS WEB RECEIVE or WEB
    CONVERSE command, where the transaction PROFILE has RTIMOUT set
    to NO (wait indefinitely), unexpectedly experiences a socket
    read timeout of approximately 18 hours (65,535 seconds) instead
    of waiting indefinitely for a response from the remote server.
    

Problem conclusion

  • The DFHEIWB module has been corrected to ensure the RTIMOUT
    value is correctly passed.
