You're suprised at that? I'm not. Here's a Linux-based web server I
access a lot that uses Apache (and is soon about to run *my* Lisp
application, too):

    % uname -mrs
    Linux 2.4.3-12.2RS i586
    % uptime
      9:56am  up 295 days,  3:26,  1 user,  load average: 0.35, 0.13, 0.10

*Only* three months?  ;-}  ;-}

    % uname -mnrs
    FreeBSD 4.6-RELEASE i386
    % uptime
     7:52AM  up 434 days,  3:09, 15 users, load averages: 0.00, 0.00, 0.00

Note: That's my home/business workstation/server. Now that it's been up
for more that a year[1], I suppose I really should take it down long enough
to upgrade to FreeBSD 4.9-RELEASE (which is what's on the laptop).

Not very many at one time, to be sure.  ;-}

Dunno 'bout Edi, but I am[2]:

    % psql -V
    psql (PostgreSQL) 7.3.4

    less than a minute, but each quite sufficient to crash/reboot the
    machine! -- I finally bought a UPS. It works quite nicely.
