PQ99465: INCORRECT RESPONSE CODE SENT DURING SERVER SHUTDOWN | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

![]() APAR status Closed as program error. Error description The WebSphere Application server is sending a response code of 500 for a request that is received after the server has entered shutdown. The Http Transport should send a 503 response if server quiesce has started.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server users of the * * Http Transport. * **************************************************************** * PROBLEM DESCRIPTION: After AppServer shutdown has started, * * the Http Transport will continue to * * accept requests on sockets that are * * in KeepAlive state. When the request * * is dispatched it fails because the * * application has been stopped. This * * leads to a high number of request * * failures during failover processing. * **************************************************************** * RECOMMENDATION: * **************************************************************** The KeepAlive loop in HttpConnection will only check for server shutdown at the end of request processing. That means that shutdown could start while HttpConnection is waiting for the next request. If it has, the next request that is received will fail when it is dispatched because the applications have stopped. This results in a response of 500, Internal Server Error.Problem conclusion HttpConnection.readAndHandleRequest() has been changed to check the server status after reading the request but before beginning to handle it. If shutdown has started, a status of 503 will be returned without further processing. In the scenario where an HTTP Server and plugin are being used, this will allow the plugin to detect server shutdown and failover to another server without losing the request. The fix for this APAR is currently targeted for inclusion in fixpack 5.02.10 and 5.1.1.4.
