APAR status Closed as fixed if next. Error description When TCP/IP fails, WebSphere for z/OS runtime address spaces are expected to go down. But they don't.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0 for z/OS and OS/390. * **************************************************************** * PROBLEM DESCRIPTION: If TCP/IP terminates, the WebSphere * * Application Server Control Regions log * * it as an error, but do not terminate. * * When TCP/IP comes back up, the Control * * Regions do not recognize it and will * * not resume listening for work from * * TCP/IP. The Control Regions must be * * manually restarted to resume receiving * * work from TCP/IP. * **************************************************************** * RECOMMENDATION: * **************************************************************** While TCP/IP termination is recognized as a failure, no action is taken by the Control Regions other than to log the error. The error surfaces with AIORV=-1, AIORC=7Ax (122) which translates to EDC5122I Input/Output Error (EIO). The Control Regions stay up, allowing Daemons on other systems in the sysplex to continue forwarding remote clients to an unreachable Control Region. The Control Region does not watch for TCP/IP to return and does not take any action to resume listening for remote connections when communications are again possible.Problem conclusion Temporary fix Comments This APAR is being closed FIN with concurrence from the submitting customer. A solution to this problem will be delivered in a WebSphere Application Server for z/OS and OS/390 release within the next 18 months
