Well sometimes you don't need to upgrade and you aren't connected to the
internet directly.
elephant: {25} uptime
5:54PM up 1756 days, 7:07, 2 users, load averages: 1.04, 1.01, 1.00
elephant 4.9-RELEASE FreeBSD 4.9-RELEASE #0: Mon Oct 27 17:51:09 GMT 2003
This machine is semi-retired now but for its first three years it was
the database server (ads, reg, hit logging etc.) for a large website
(> 300,000 pages/day). It also handled the queries for a
monthly reports server that created detailed reports
for about 5000 companies that had content on
the site. I didn't keep track of the connections then but its
replacement is doing 28,527 conn/hr.
This was on an internal network that was firewalled from everything
but port 3306 on the webserver IP, and a couple admin IPs. It was a big exercise to
replace it as the databases were quite large (48G) and it took a good fraction
of an hour to make the occasional snapshot for starting a new replicator
when needed.
FreeBSD really is one of the most stable OSs even under a pretty
good load.
Cheers,
Charlie
