Good point

I am not using that log. I have a custom log. Basically, as I log at the application level, whenever the application ends, it will establish a log. However, I am not sure I can get the reason of the shutdown by using that approach. Is this why you mention this LogEventOnRecycle Event Viewer approach so I could get additional details?
