I have a ASP.NET web application, hosted at AWS server(windows 2008 R2 with IIS7.5). Yesterday a weired thing happen with my application, suddenly application stopped working. When I checked IIS log, IIS was getting requests with status 200(OK) but application was not getting any request. There was no application log, DB entry nothing. after some debugging when I hopeless I just restarted server and application start working. I had also checked Event Log for any critical error. I found an error in event viewer.
-------------------------------------------------------------------------------------------------------------------------------------------------------------The following exception was thrown by the web event provider 'EventLogProvider' in the application '/buildmytest' (in an application lifetime a maximum of one exception will be logged per provider instance):
System.Web.HttpException: The EventLogWebEventProvider provider failed to log an event with the error code 0x80070057.
at System.Web.Management.EventLogWebEventProvider.ProcessEvent(WebBaseEvent eventRaised)
at System.Web.Management.WebBaseEvent.RaiseInternal(WebBaseEvent eventRaised, ArrayList firingRuleInfos, Int32 index0, Int32 index1)
