[Novalug] need help: server freezing / locking up

[jerry w]

I'm amazed that you haven't had problems
with the data with all the freezing...

I would think inconsistencies would be
introduced each time you hard poweroff
the machine when it freezes
(like incomplete writes), so
maybe just stopping the machine
(freeze) is a better solution than
having problems with the saved
disk information upon reboot?

(i.e. it's a feature not a bug)
