On my "current" box I've been running 4.X- Stable, but it's a single cpu machine. It's primary function will be an Apache web server. I'm very interested in running 5.0 so that I can take advantage of the SMP enhancements, but I'm also worried that it may not be very stable for my configuration. Assuming that those on this list have a lot more experience running FreeBSD with multiple CPUs, what are your recommendations? Specifically, should I stick with 4.X-Stable, or start using 5.0? Are there widespread problems with 5.0, or do I have a pretty good chance of having a stable system? It's not mission critical in the sense that I can't build it, then rebuild it if it turns out to not work out well, but that's obviously a lot of work and wasted time that could be avoided if I can get a warning that there is little chance 5.0 is stable enough to run on my configuration. Also, if you have a recommendation for one or the other, are there specific kernel/tuning parameters to make sure I include or to make sure I avoid like the plague? Thanks in advance for the benefit of your experience and advice, Thomas
