Hi.. i've got the serious problem..

In my ASP.NET 2.0 application I'm using COM dll file referenced by interop dll.
I'm using few properties from in one of the objects made from this library class.

Problem is that i get "IIS Worker Process stopped working and was closed" error on my server. The script is working too long and then the process is stoped.

I located wchich line of code causes the crash. It's invocation of one of the methods that i used, and it has following form:

int PerformInitTransaction(void)

This method connects to the Bank server and returns the status of the operation, so maybe its the problem with the permissions or sth?

This situation shows up on the IIS7, WindowsServer 2008, ClassicAppPool.
The problem didn't show up on my local IIS7 Vista server.

Please, help me with that issue.
Thanks..

PS. I'm also attached analyze of minidump made in windbg.

re: IIS Worker Process stopped working and was closed and unmanaged code...

Can you try the following:
1. Temporarily run your application pool under an account with administrative privileges and see if you can reproduce the error.
2. If you can reproduce the error, then write a quick Windows Application test app and run the same code interactively (i.e. clicking a button on a form, rather than invoking a web application).

If it works interactively, but not in a web app, then you may need to control the threading in the web app to make it more like a Windows form. You might need the ASPCOMPAT option, or you may need to make sure COM calls are serviced on the same thread that instantiated the COM object.
