Usually it is due to overheating.

Read that web site. There was a HUGE fiasco over some stolen capacitor recipe that was then used on tons of boards which lead to the caps overheating and bulging/leaking. Basically if a capacitor gets too hot gas expands inside and it breaks the little X on the top. Lots of old capacitors slowly dry out over time which can also lead to overheating and then bulging.
