Error correction? I don't understand.
Isn't having certain applications know the system has crashed and is now
fully functional a neccessity,
Besides, what security knowledge could you gather from knowing that the system has been cycled, and is functional again, that you couldn't otherwise gather from watching connections drop. Also a program that stores a timestamp every minute could easily figure out the system it is running on has crashed because there will be a big gap between the current timestamp and the last one.
