IIS problem, web application
When I use the web application, the application logs me out. I think it might be an IIS recycle.
EventViewer Message:

Tess Ferrandez has some great tutorials and information on how to use DebugDiag and WinDbg to nail down why this is happening:
There's also a lab to walk you through analysing worker process crashes:

I ran into exactly the same symptoms, and the real reason was that I accidentally created an infinite recursion, which in turn caused a stack overflow. Please note that you need to restart the app pool after correcting the error.

I know I'm late, but I just debug a similar problem with WinDbg. I finally managed to find the cause of the problem.
It's a reported bug at microsoft: http://connect.microsoft.com/VisualStudio/feedback/details/330926/cryptostream-flushfinalblock-fatal-on-64-bit-os-if-bytearray-is-null
I just add this to the discussion as a lead for others who search the web.

I solved this problem. Solution Steps:
- First I open ControlPanel> ActionCenter> Problem Reports
- I saw list of problems. and my IIS Crash problem.
- I entered item detail and save it is dumps.
- I downloaded Windbg then open this dump with it.
- and enter command
!analyze -v
Windbg analized and show a text like this:
GetPageUrlData failed, server returned HTTP status 404

So I added this code to Decrypt Method: if (String.IsNullOrEmpty(value)) return String.Empty;
public static string Decrypt(string value)
{
SymmetricAlgorithm algorithm = SymmetricAlgorithm.Create();
ICryptoTransform decryptor = algorithm.CreateDecryptor(EncryptionKey, EncryptionVector);
// I control value
**if (String.IsNullOrEmpty(value))
return String.Empty;**
byte[] encryptedBytes = Convert.FromBase64String(value);
MemoryStream memoryStream = new MemoryStream(encryptedBytes);
CryptoStream cryptoStream = new CryptoStream(memoryStream, decryptor, CryptoStreamMode.Read);
...
}
problem was solved.

The ASP.NET worker process is crashing with Access Violation. This is usually a result of dereferencing a NULL or an invalid pointer. Attempting to access a null reference in C# normally generates a managed exception which ASP.NET is capable of catching, I would assume that your web app is using COM interop or is invoking unmanaged (C++) code that crashes.
Unfortunately, that's about as much as we can tell you from the info above. You will need to debug your process to understand the exact cause of the crash.
