Our office webserver is running Slackware 13.37.0, kernel 126.96.36.199-smp. Fives times this year this computer has unexpectedly crashed; most recently, twice in the past 3 days. When I check the console, all I see is output as in the attached image. Not sure what this is telling me, if anything. It looks sort-of dmesg-y, but a normal dmesg doesn't have any [ 251.xxxx] in what I assume is the log level prefix. Nor does dmesg show the 2nd set of bracketed codes, e.g. "[<f8a8e118>]". I don't know if this output indicates a failed reboot or if it is some kind of diagnostic dump while running, ending in a system halt.
Does this mean anything to anyone? I'm trying to figure out what could be the cause before I start randomly replacing components.
hitting the reset button successfully restarts the computer, albeit with fsck's because the drive was not properly unmounted.
