Re: somewhat worrying messages from syslog

Hi all,

After a clean install of fc3 (long story), Ive managed to finally update
the system with redhat packages, including the latest kernel (2.6.11-?).

As I was downloading some further packages from the Planet Ccrma apt, I
recieved this message from the syslog via terminal:

Apr 13 04:13:32 localhost kernel: CPU1: Temperature above threshold
Apr 13 04:13:32 localhost kernel: CPU0: Temperature above threshold
Apr 13 04:13:32 localhost kernel: CPU0: Running in modulated clock mode
Apr 13 04:13:32 localhost kernel: CPU1: Running in modulated clock mode

I have a P4, w/ hyper-threading and using a Shuttle designed
case/cooling system (thermal). Its currently 4.15am, so not sure if
cron's are being strange. Its a moderate room temperature.

I rebooted into the old kernel installed on the FC3 disks, but have
recieved the message again. My system-monitor is all over the place with
CPU usage, but stable with RAM usage.

Is this damaging? Any help? Ideas?

At this stage Im going to shutdown the computer and use Windows XP for
the next few days until I get a clearer picture of whats going on - will
that help the situation if this is a Linux related issue?

Can I be confident that the system would shut-down before any actual
damage occured?

Im also due to give the case a good vacuum.

Hope Im not over-reacting,
Niko


It is an indication of the thermal monitor on your processor.


XP may not give you a warning about your processor over heating. If it gets to hot, your processor will die. At least Fedora noticed it and changed it's operating mode to minimize the heat build up.

Better getting a message as to why your machine seems slow than to just have it happen.

Shutdown and clean you system if it requires it. It may stop the over heating. Also check that nothing is blocking the air flow at any vent.

When the crons run, the system monitor will go every which way as the different processes are run.
