Hi

 

Thanks for your reply. I have adapted our implementation of the IHttpApplicationUserAdapter interface so all exceptions are caught.  This is how we implemented it:

Unfortunately, even after this implementation we experience the same problem. After a deployment or when the worker process is recycled the CuteChat application sometimes has trouble loading or initialising. If this has happened once, CuteChat does not recover until the next IIS restart. In a productive environment this is a big problem.  It really seems to me that this is a problem of initialization. When the initialization phase is over without any errors, CuteChat works fine. However, if an exception occurs, CuteChat cannot recover. The exception that is written to the log file is the following:

Please have a look at it as we cannot go online like this.

 

Thanks
