Hi All, I've got a pair of identical production Xeon SMP webservers running FC1, Apache2, PHP, Postfix and a stack of custom userland software. In the last 2 months, uptime has steadily been decreasing, until last week I couldn't get the main machine to stay up for longer than 8 hours at a time. I moved the system to the twin machine, and it was crashed the next morning. I've as of yet been unable to get any sort of useful messages in syslog or out my console port. So I finally broke down and built up a vanilla 2.4.25 kernel using the i686-smp config file, installed it, and the machine has been stable for a week. What's wrong with the fedora kernel, and how can I track it down? Thanks --erik
