Production error

I keep getting an error in my production environment but not in my development. The error is pretty severe, it occurs at different times and simply loops a display message that says something like "Submitoperation failed, please inspect each Entity.ValidationError in EntitiesInError", until there are so ma开发者_如何学编程ny popupwindows that the app crashes. How can I debug this, when it's in my production environment, I really can't reporudce this error locally.

the error was actually caused by me having placed a submitreport method in my unhandledexception method, and although inside try{}Catch{} blocks, it continously failed out loud.
