I have a ubuntu 11.04 box running 24/7. It started to crash any couple of days recently.
I checked in kern.log, dmesg... but did not find anything there. Is there a specific place where shutdown reason (temperature, or whatever) are logged ?

Do you have monitoring for you server?

Actually, my answer to this would be: Please add monitoring for your server if you do not have. You should have at least: cpu load, cpu temp, disk usage, disk temp, disk IO, NIC traffic.

Just chose one you can easily install, maintain. Any or a combination of these would work (not a complete list): mrtg, cacti, zenoss, nagios etc.; with proper plugins, snmp or rrd scripts.

Check the charts for clues after a crash happens.

I do not have monitoring as until now there was not much running on this machine, but I'll install a couple of those, thanks. – Luc Mar 31 '12 at 15:57
I have added monitoring to my routine of installing a server. The time spent is minimum in comparison to the benefits if you need to investigate or to troubleshot some random problem. – Paul Mar 31 '12 at 16:48
without installing dedicated monitoring tools, does ubuntu provide some stuff out of the box ? – Luc Mar 31 '12 at 23:47
asa far as i know none that can easily display charts or data. – Paul Apr 1 '12 at 5:41
Go for something like Zabbix. Easy to install and get started with – Industrial Apr 2 '12 at 7:50

I have a unbuntu 11.04 box running 24/7 for something like 2 years now

You do realize this is impossible, right ?

Either it's not 2 years, or you upgraded it.

CHeck the upgrade logs for any issues.

Sorry, typo I'll update my post. Obviously I updated it several months ago. I just meant the hardware is running since 2 years. Sorry for this. – Luc Mar 31 '12 at 15:06
