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).
