Well, I don have any idea of why we get this error. I see a lot of these in my elmah log.
Any ideas how to fix and why this occurs .
You do not have anything to fix - what this say is simple. The other point that view your page is close the connection before the full processing of the page - an in this case what's happens from your side is that you continue the page render and you get this throw.
if you have some pages with long time processing you may check time to time if the user is still connected using the
Response.IsClientConnected
and maybe stop the processing.

Have no X(1) in my system, no idea where it is coming from and why it occurs just from time to time. Is the framework putting it there?
Running out of ideas here.
Has anyone had this problem before?
Thanks a lot for the help.
The issue has to do with ASP.Net Cookieles feature, that is where the X(1) comes from.
Give a look to the following link

It is a normal Windows and .NET installation. Reflection is supported. Clearly there is another factor here. We don't have enough information to help however. A stack trace is important for things like this.
You probably need to make sure the DLLs you use all have the Copy Local property set to True. Like:
http://stevesmithblog.com/blog/asp-net-mvc-2-and-windows-azure/

when doing a multitude of things. It happens randomly, and sometimes happens doing the same exact thing that we just did without an error. Even when we catch an error in javascript sometimes, it still throws this error on the backend. Sometimes it navigates the user to a generic "Server Error" page as well.
What is a way we can handle this and display some information about the source of the issue? This stack isn't showing much...
Does your action method (or controller) has the [HandleError] attribute set on it? If that's the case and you don't have Error.aspx, then you will see this error. If you remove the [HandleError] attribute, you will be able to see the actual error.
I'm not able to open the file when I click on the link on page in MVC. I get the following message. I've added the impersonation in the code. I'm able to delete and save the file.
Access to the path '\servername\folder1\folder2\folder3\foder4\filename.pdf' is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path '......same as above....' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

I think the error message is more than clear, it even tells you what to do which is rare. Your web site runs under a special account with limited privileges. Depending on the version of IIS you are using this account could vary. So you should consider granting read access to this account to the remote folder you are trying to access, which according to the exception you are getting is \servername\folder1\folder2\folder3\foder4.
You are saying that you've added impersonation, but impersonation works only for local resources. In your case it seems that you are trying to access a remote server (a remote share). In this case you need delegation and not impersonation. So you could configure your site to run under a domain account which has read access to this remote share.
I just launched my tiny webapp on my humble dedicated server (Win2003)... running ASP.NET MVC, LINQ2SQL, SQL Express 2005, and IIS6 (setup with wildcard mapping)
The website runs smoothly 90% of the times. However, on relatively high traffic, LINQ2SQL throws the error:
Specified cast is not valid
This error is ONLY thrown at high traffic. I have NO IDEA how or exactly why this happens. Caching did not remove this problem entirely.
Anyone seen this problem before? are there any secret SQL Server tweaking I should've done?
Or at least, any ideas on how to diagnose this issue? because i'm out!

We used to get these exceptions if we first got a exception like this "System.InvalidOperationException: There is already an open DataReader associated with this Command which must be closed first." or " A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)".
The first exception occur for a different instance of the DataCOntext then for all those that then are following.
After some research and asking in this thread , I found that the reason was that I did not dispose the DataContexts. After I started to do that, it dissappered.
Sounds like maybe a race condition, or perhaps a rare bug that is only correlated with high traffic because that when most of your requests occur.
