Well now ... that very much depends on where you *got* the server OS and how you administer it. If you're talking a correctly-maintained Windows 2003 Server installation, or a correctly-maintained Red Hat Enterprise Linux installation, or any other "branded" OS from Novell, Sun, HP, etc., I'm guessing such crashes are much rarer than what you've experienced. And you're probably in pretty good shape with Debian stable and the RHEL respins like CentOS. I can't comment on Ubuntu server or any of the BSD family -- I've never worked with them. But you should be able to keep a "branded" server up for months, with the exception of applying security patches that require a reboot. And *those* can be *planned* outages! Where you *will* have some major OS risk is with testing-level software or "bleeding edge" Linux distros like Fedora. Quite frankly, I don't know why people run Fedora servers -- if it's Red Hat compatibility you want, there's CentOS. -- M.
