I recently updated our production site and now encounter some strange errors.
Once in a wile I will receive a NullReferenceException in Page_Load when trying to access a web control or user control. The error only happens on the production server and it happens something like 1 in 10 page loads. It is always the same line .cs causing the error. I moved the line to PreRender for the control but the same error was than caused by a different control. I do not think that the solution is moving everything to PreRender, something else must be wrong and causing these errors.
