One of my servers is used as an Internet gateway, so it hosts many network services, e.g. e-mail, DNS, NTP, DHCP etc.

That one (which runs FreeBSD) is rebooted perhaps once per year or even more seldom, when I do a kernel update or a hardware upgrade. If I would need to restart it for other reasons, e.g. memory leaks, that would be a failure of the OS.

On the other hand, with my main desktop PC (which runs Linux), frequently I leave it running some overnight job, but when that is not needed I always shut it down for the night.

I have never understood the people who like hibernation, because my computer has always been optimized to power up in some 10 to 20 seconds at most, and shaving a few extra seconds per day from that seems meaningless.
