I'm going to copy a bit of mail that I sent to someone privately.
FreeBSD 4.11 can survive a simple burn-in test. FreeBSD 5.X and
6.1 can not. Here's what I wrote earlier.
Take a server. Configure for SMP, add quotas within jails and
basic IPFW protection with a few hundred dummynet pipes for b/w
throttling (less than 10,000 total IPFW lines). Load the machine
a bit so that it constantly maintains a 3 digit load and run
sufficient active processes to keep it in moderate swap state.
The result of that minimal-effort test yields machines which can
not maintain 30 days of uptime (most fail in under a week).
And don't even THINK about snapshots in 6.1 or earlier.
>THAT< is why people who run servers, with jails, quotas, ipfw and
moderate load keep complaining about 5.X and 6.1 and begging for
4.11 support to be extended. Just because someone has a few FreeBSD
boxes running light loads and not using the features that we NEED
does not mean that any the port 4.11 releases to date are stable.
