I flew out of Dulles Airport a couple of days ago and found the Flight Departures monitor displaying some interesting information. Although you can't tell from the picture, the dialog showing is the "System is running low on virtual memory" that we have all seen at some point or the other.

The dialog stayed on the screen for the entire 45 mins. I was waiting for my flight to board. Although this is only an information screen, it still makes you wonder how much thought goes into fault tolerance and recovery on the systems that power such displays?
