On older aircraft one of the more common occurrences is that if one bleed/pack fails, the remaing bleed will be supplying both ac packs and does frequently lead to overloading of the precooler or temp/press controls on the remaining system resulting in a second bleed failure and press'n loss.
Not a problem on the Boeings... as only one bleed source is permitted to operate one A/C Pack. Don't know about the Douglas or Lockheed, or Airbus.
