Question Debian Freezing totally!


I have the latest Debian installed and updated with apt-get.

But my server freezes all the time. Sometime it can be just after a couple of hours and sometimes it can take days.


When the computer freeze there is no way of communicate with the computer. Leeds on the computer is blinking and the fans are still spinning. But otherwise no communication is available.

I have checked all logs in /var/log/ but non of them shows any problem. I'm now running memtest to check the ram and that seems to go correct without any errors.

Is there anything else that can make the computer freez. Something in Debian? Is there anyway to check the temperature in the computer? Can the computer freeze for temp? It doesn't feel that hot thou.


Anyone that can help me out. It's really annoying since I need to be sure that my network home is up.


----edit----
Memtest run without an error for 14 hour.


I now before one freeze got some syslog messages hope they will help:

The system will freeze if the cpu exceeds its maximum temp. You can install lm-sensors and monitor cpu temps via the command line. If you are using a gui on the server you can install GKrellm to have a constant display of several things. Best thing to do if you suspect this is to get an application called cpuburn-in and stress the box and see if it crashes. You will then know the cause.

Thanks for your reply.


I will test cpuburn and see how it reacts. Have also seen now if I'm not running vmware servern on the machine the freezes is not that freqvent. So if that's beacuse there is some bug in vmware server or that the processeor works extra hard and there fore freeze I do not really know.
