When was the last time you dismantled and cleaned the machine?
Arthur:
Three monts ago? Seems clean, though.
- I changed the memory DIMMs.
Before or after the rebooting started?
- Disconnected the machine electrig plug.
- Pushed RESET button for about a minute.
I repeat: since the power outage, it reboots every 1.00.19, approx.
tried coming up in single user mode and running something like:
e2fsck -y -c -k -v -C 0 /dev/rootdevice
yes, normally ext3 does not have problems with power drops and such, but it
can over time build up some things that need cleaned up, and at a minimum a
read-only media check can be a good thing {read-write is better, but takes a
looooong time}.
Tim:
could not be a cron issue, that would lead to exactly 1 hour rebooting.
Every 3 reboots means 3 hours and a minute (look my previous logs).
How long does it to reboot? ~19 seconds?
How long does it take for the program that is getting started at 1 hour after
the machine comes up, to use enough power|memory to cause a fault? ~19 seconds?
BTW been here and bought the tee shirt... My machine had a problem of using a
little more current than the wires supplying it could carry, while trying to
get cron.daily done and doing it's other work.
suggestion: bring the box up in runlevel 3 and come back to it about 58
minutes after you boot it, you might actually see the kernel give an OOPS or
panic. [If you don't have the patience to do that, there is the option of
setting up a serial console to another machine and logging the console there.]
reason for runlevel 3: so you see console messages instead of GDM.
# ls -l /etc/cron.hourly/
total 0
Means little, as if the machine has not been able to complete .daily or
.weekly or .monthly in that time period, then it will start running those at
~1 hour after boot.
try:
ls -ltr /var/spool/anacron/
# at -l
# uname -r
2.6.26.5-45.fc9.i686
