i Apache HTTP Server configured for SSL that is associated with an IBM 500 error code in websphere application server WebSphere Application Server v8.5 or later profile, an HTTP 500 Internal Server Error might occur when accessing your web 500 internal server error ibm http server application. Symptom HTTP 500 Internal Server Error received in your web browser when accessing your web application URL AND The following errors appear in the plugins_root/logs/web_server_name/http_plugin.log file.

accept SSL communications. Environment IBM i; IBM WebSphere Application Server v8.5.5 and later Diagnosing the problem Verify a HTTP 500 Internal Server Error is received in the web browser when accessing the web application's URL. Check the plugins_root/logs/web_server_name/http_plugin.log file for errors. The http_plugin.log file is typically located in the /QIBM/UserData/WebSphere/AppServer/

Enterprise Extensions' long running functions such as builds, scans, queries, or searches, 500 Internal Server Errors can occur if the serverIOTimeout error: lib_security: logsslerror: str_security (gsk error 408): gsk_error_bad_keyfile_password value in the IHS plugin is set to the default of 60 seconds. Symptom Similar errors will show in the dialog windows and in the logs such as: 2013-11-14 12:40:41,199 [WebContainer : 12] INFO http://www-01.ibm.com/support/docview.wss?uid=nas8N1019946 com.ibm.team.jfs.app.http.client.JazzHttpClient - I/O exception (org.apache.http.NoHttpResponseException) caught when processing request: The target server failed to respond or CRJAZ0098I The "com.ibm.team.build.internal.common.ITeamBuildRequestService(/com/service/com.ibm.team.build.internal.common.ITeamBuildRequestService)" service fails. The server returned the HTTP error 500 with error text "Internal Server Error". Cause Due to increased network traffic or long running functions, the WebSphere Application Server running the Rational Team Concert CCM application may not respond to the build agent, z/OS, or the client http://www-01.ibm.com/support/docview.wss?uid=swg21663293 within the time required or vice versa. The IHS server being the intermediate handler will not process the request from the application server within this time and an ambiguous 500 Internal Server Error is returned. Timeout values can be set higher for the build agent and the client to overcome individual problems, but if IHS is running as the reverse proxy, the 500 errors may still randomly occur. There have been some defects resolved that do affect specific timeout issues. If after applying these, the 500 Internal Server Errors still occur, you should investigate the IHS plugin settings. Environment Enterprise Extension dependency builds, promotions, scans, context aware search, or any function that is long running through the IHS reverse proxy with WebSphere Application Server 7 with a default value of 60 as ServerIOTimeout can cause these errors. Diagnosing the problem The best method of diagnosing is to enable logging in the IHS plugin and monitor the access.log, error.log, and httpd_plugin.log for the response times and any 500 errors over a specific time frame. To enable logging in the IHS http and plugin: Enable mod_status Enable mod_mpmstats Set LogFormat to include %T Enable the http plugin trace In the httpd.conf, this example shows mod_mpmstats

It runs fine one one server 500 error instance, while on other instance, the server returns 500 (Internal Server Error) when transaction time exceeds 60 seconds. Application runs fine on both the server when transaction time is less than 60 sec. General transaction properties in Application servers > server1 > Transaction service are identical on both the server instance. I believe its not a coding issue and in that case its something related to server settings. http websphere-7 share|improve this question edited Oct 3 '14 at 18:06 AlvaroAV 4,03572659 in websphere application asked Oct 3 '14 at 17:52 Jenson 58113 Add full stack trace, it is too little info to tell something more than to double check Transaction service settings. –Gas Oct 3 '14 at 18:28 There is actually no error message at the server side. After 60 sec of transaction server returns status 500 to browser. I believe it is related to ServerIOTimeout property in the IHS Plugin component. –Jenson Oct 3 '14 at 20:00 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted Yes, you are correct. Look at the definition from documentation: The ServerIOTimeout specifies whether there is a time limit for how long the plug-in waits to send a request to or receive a response from the application server. The default value for v7 for this parameter is 60 seconds, which is too low for your application. You have to change it. You can just edit it in plugin-cfg.xml (see details in the first link). However if you often regenerate your it, it will be better to change it in the server configuration ( Servers > Server Types > WebSphere application servers > server_name, and then, in the Additional Properties section, click Web server plug-in properties - details in the second link). The third link gives you some more details how different values of the plugin parameters affects request handling and retries. See also: plugin-cfg.xml details Application Server p
