Tru dat, but take away the exaggerated $10k/minute cost of an individual production server, and the point still stands, that the manual restart as security measure is a fallacy.  I cannot say there is never a situation where manual restart is beneficial, but I *can* say that auto restart is better in most situations, because most crashes are caused by accidental conditions for which the best reaction is to restart, and then research root cause.  More importantly, I can say, that even when a crash occurs as a result of malice, the manual restart is ineffective as a countermeasure.
