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. /\/\ \/\/
