Application_End trigger reason

Question

User1417140358 posted

I have a web service hosted on Windows Server 2008. I made sure to turn off all the ways to recycle the IIS. Still inconsistently I am seeing Application_End event getting triggered in my Web Service application (Global.asax).

I went through Event Viewer, custom log files created in Catch block, Debug Diagnostic tool but no luck.

Rarely I see Application_Error event occurred.

In Global.asax file I tried putting below code to log but lo luck.

System.Exception ex = Server.GetLastError().GetBaseException();

LogInfo(ex.ToString()); //Your own logging function...

Server.ClearError();

Is there any other way to find the reason why Application_End event is getting triggered?

As per by default setting([default settings - Rapid Fail]) of IIS7.5 , application pool will recyle after certain amount of error. May be that's why your application_end is calling again and again after certain time period

Please put apllication_error on global.asax  And check if there is error you can catch up of check event viewer.

protected void Application_Error(Object sender, System.EventArgs e) {

System.Exception ex = Server.GetLastError().GetBaseException();

LogInfo(ex.ToString()); //Your own logging function...

Server.ClearError();

}
