Hi,
This morning my server started rebooting itself constantly for about 15
minutes. Although the last log seems to indicate that at least 1 crash
occured, no core dumps are to be found in /var/crash and I couldn't
find anything pertinent in the system logs. I'm thinking flaky hardware
but, short of plugging in a monitor and sitting watching it, is there
anything I can do to trace the source of the problem? I ran memtest86+
on the machine not too long ago and I'll do so again in the meantime.
Thanks.
