Quite often (50% - 60%) of the time, there is not enough information from an OOPS to know what happened. Ive got a huge pile of oops reports where all anyone could do is shrug their shoulders and say 'well, if it happens again let me know. i dont have the slightest clue because theres not enough information from an OOPS to tell.'
A crashdump in those situations would have been extremely valuable.
