This system (this one, right here, that I'm typing on) is dual processor, and I installed it fresh with 4-CURRENT just after RELENG_3 was branched. Except for an excursion on RELENG_5, it's always run -CURRENT. Sometimes I'd go a year without updating, sometimes a week. It's running -CURRENT from a couple weeks ago now. Sometimes it's a bit twitchy, but I think running X has a whole lot to do with that, since MP systems under heavier loads without X would do just peachy with the exact same build that was flaky here. -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
