I'm in a dedicated server service and I tried to check with them on this issue but they said they're not able to check further as I did not subscribe to their managed server package and the technician seem to claim that nothing is unusual and if I would like to do a hardware diagnosis they'd need to take the server down for one day. So I was wondering whether anyone can tell what are the possibilities this could happen in /var/log/messages:

As you can see from the above log, the temperature is normalyl logged every 5 minutes from the CPU sensor but stopped at 6:00 am. I did a reboot on 19:10 on Feb 15 and everything seemed fine. I checked my server logs and there was no indication of a DDOS attack and this looks to me like a server crash due to temperature issue, but other than that, what could be the possibilities? Could I get some sort of compensation from my dedicated server company due to this ?
