Quick survey question. 1) What do you consider the risk level of (a) hanganalyze and (b) system state dump? Would you run this on a loaded production system? What if it's experiencing some kind of serious problem but a crash is not imminent? First-time problems vs recurring problems? 2) What actual experiences have you have with these? Good and bad stories, please specify versions of DB and OS. -Jeremy -- http://about.me/jeremy_schneider
