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.
