    I am working on an ASP.net application, Inconsistently the application crashes with following error message by message it seems Worker Process/IIS crashes.

    I have observed that before actually application crashes, multiple times ASP.net warning gets generated.

    Some time application automatically recover from this state and start working but the last resort is reset the IIS.

    Exception type: NullReferenceException 
Exception message: Object reference not set to an instance of an object.
at System.Web.HttpApplication.PipelineStepManager.ResumeSteps(Exception error)
at System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb)
at System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context)

    Can someone help me with what may be wrong here, is there a bug in Microsoft IIS or Framework. I am using IIS 7.5, Windows 2008 and Microsoft UIP framework.
