I dunno, but two of my FreeBSD machines at home have been up for a
reasonably long time:

    % uptime
     7:38PM  up 395 days, 11:09, 12 users, load averages: 0.00, 0.00, 0.00
    % ssh ${ANOTHER} uptime
     7:38PM  up 1006 days, 13:40, 0 users, load averages: 0.15, 0.03, 0.01
    % 

Note that 1006 days is exactly the time since I installed a small UPS!! ;-}
Before that, they were crashing several times a month due to short-
duration power outages (typ. under 5 seconds). I explicitly rebooted
the first one [my main server] about a year ago for some reason, but
I forgot why. Mostly they just run & run & run, as does the CMUCL
process that runs a persistent application server [behind Apache].
