![]() APAR status Closed as program error. Error description When we add the following two lines to the http.conf file, the Dr. Watson error returns. ----------------------------------- LoadModule ibm_app_server_http_module D:/WebSphere/AppServer/bin/mod_ibm_app_server_http.dll WebSpherePluginConfig D:\WebSphere\AppServer\config\plugin-cfg. xml ----------------------------------- Without the two lines, JSPs are not processed. What seems to kick off the Dr. Watson is a pollinog from another server that does this (taken from the HTTP access log): "HEAD / HTTP/1.0" 200 0Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server version 4.0 * * users of the IBM Http Server and Apache * * webserver plugins. * **************************************************************** * PROBLEM DESCRIPTION: The webserver will periodically trap * * when a request with no host header * * is sent and the plugin-cfg.xml * * contains a non wild carded virtual * * host definition. * **************************************************************** * RECOMMENDATION: * **************************************************************** When the host header wasn't sent, the plugin would attempt to do a strcmp (string compare) on a NULL pointer if a non wild carded virtual host was being used. This would result in a trap in the webserver process.Problem conclusion Prevent the server from trapping in this testcase by using localhost for the server name if the host header isn't sent.Temporary fix Comments
