At my last job we put a policy in place where no system would have a
greater than 150 day update, unless it had extenuating circumstances.
What I discovered in general was this:

- systems that haven't been rebooted in a while sometimes gather cruft
that has not been properly laced into the startup. so it doesn't come up
on its own. Rebooting frequently ensures that people remember to do that

- any system that "MUST BE UP ALL THE TIME" should be redundant. If it
is not redundant and it is that important then that service is a pretty
precarious position.

- reboots ferret out problems in hardware that you don't always see
until a powercycle. Like a disk that will just keep on spinning provided
it is never stopped.

I agree with religiously rebooting boxes.
