On our development environment system works fine but on Live system sometimes buttonClick action generates below error. If i press back 1-2 times it works without generating error.
On the live system error, it still shows my local path. Can this be the issue?
Thanks for your help

To answer one question: when compiling .NET code into DLL, the local path of the source files is being stored in the assembly - not sure if only when compiling in Debug or also in Release.
Anyway, add the generated .PDB file to the same folder containing the DLL file on the server and you'll also get line number (instead of cryptic +3690): having this you can identify the exact line causing this error.. post this information here and we'll be able to help.
It seems you might have the page life cycle wrong and you might be setting a variable at a certain point and expecting that variable not to be null when you are accessing it.

You will get this error if you try to host a web application using a 32 bit dll on a 64 bit server.Quick fix is to set "Enable 32 bit applications" flag to true in AppPool Advance Settings for the site.Select the Application Pool used for the application and the set that flag to true.Restart IIS.

I am writing WebEvent in my asp.net Application and it is working fine in both my development and production region.However, When I analyze Event Logs in production server for past couple of months.I see below event
The following exception was thrown by the web event provider 'EventLogProvider' in the application '/(MyApplicationName)' (in an application lifetime a maximum of one exception will be logged per provider instance):
System.Web.HttpException (0x80004005): 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)
Although Occurrence is very low, still I am curious to understand why this is happening.I tried to do some research and found below link
http://forums.iis.net/t/1201176.aspx?IIS+Keep+hanging
According to this link, I may be passing some invalid argument while writing event log.
But I double checked my EventLog.WriteEntry method and I am using it in my application only in couple of places and moreover, I am passing static string message. If argument is invalid then it should occur every time I try to write event.
Can anyone please help me understanding possible cause for this event.is there any known issue when working with EvenLog?
Check your code you may be trying to perform an invalid operation.
