onApplicationStart Application scope timeouts question

If I declare an application scoped variable or object in application.cfc onApplicationStart(). When the application scope times out its now dead. I want that to persist one used for websockets but not all application variables.

What would be the best way to fire it up again.

function onApplicationStart(){
                Application.objects.chat =  WebsocketRegister("/ws/chat/{channel}", new ChatListener());
            }

After some time I get :
The WebSocket session [x] has been closed and no method (apart from close()) may be called on a closed session when I try to broadcast to it.

Should I be using a NOT ISDEFINED("Application.objects.chat") in application.cfc. Check if its there and reload it? Or is there a better way?

Thanks
