However, every time in the past this happens, re-installing the operating system fixes it. So while it's possible, I consider it unlikely and WAY TO EXPENSIVE to shotgun it that way. Point taken though, I think I'll run the RAM test program that is on the Fedora install disks. Unfortunately, I don't see how faulty hardware can cause the session messages that I keep getting. Looking again at my logs it seems they run every five minutes which led me to check CRON. the only thing that appears to be running every 5 minutes is mrtg and disabling that did not get rid of the messages. It appears that some rogue program is running in the background and I need to narrow down what it is.
