Linux Server Reboots Automatically


Dear all,

Today I got stucked around a strange problem.
Don't know why me linux reboot automatically.

Server Info :
Linux Server-5 2.6.16.46-0.12-smp #1 SMP Thu May 17 14:00:09 UTC 2007 x86_64 x86_64 x86_64 GNU/Linux
Welcome to SUSE Linux Enterprise Server 10 SP1 (x86_64) - Kernel \r (\l).

Mysql version is mysql Ver 14.12 Distrib 5.0.45, for unknown-linux-gnu (x86_64) using readline 5.0

I researched a lot & try to find the reasons :

Last time Reboot :-
reboot system boot 2.6.16.46-0.12-s Thu Jul 28 10:33 (00:06)

I read my /var/log/messages but not able to find any pointers for that.

But i found one clue :
My server reboots at :

reboot system boot 2.6.16.46-0.12-s Thu Jul 28 10:32 (00:24)
reboot system boot 2.6.16.46-0.12-s Wed Jul 27 18:47 (16:10)
reboot system boot 2.6.16.46-0.12-s Wed Jul 27 17:40 (17:17)
reboot system boot 2.6.16.46-0.12-s Wed Jul 27 16:58 (17:59)
reboot system boot 2.6.16.46-0.12-s Wed Jul 27 16:41 (00:14)
reboot system boot 2.6.16.46-0.12-s Tue Jul 26 10:50 (1+06:05)

And below shows that

Server-5:/var/log # grep "CPU" /var/log/messages | more

Jul 25 10:54:31 Server-5 rcpowersaved: enter 'powernow_k8' into CPUFREQD_MODULE in /etc/powersave/cpufreq.
Jul 26 10:52:04 Server-5 rcpowersaved: enter 'powernow_k8' into CPUFREQD_MODULE in /etc/powersave/cpufreq.
Jul 27 16:42:43 Server-5 rcpowersaved: enter 'powernow_k8' into CPUFREQD_MODULE in /etc/powersave/cpufreq.
Jul 27 16:58:57 Server-5 rcpowersaved: enter 'powernow_k8' into CPUFREQD_MODULE in /etc/powersave/cpufreq.
Jul 27 17:41:09 Server-5 rcpowersaved: enter 'powernow_k8' into CPUFREQD_MODULE in /etc/powersave/cpufreq.
Jul 27 18:47:55 Server-5 rcpowersaved: enter 'powernow_k8' into CPUFREQD_MODULE in /etc/powersave/cpufreq.
Jul 28 10:33:49 Server-5 rcpowersaved: enter 'powernow_k8' into CPUFREQD_MODULE in /etc/powersave/cpufreq.

I tried to find its explaination.

Thanks

So messages just cuts off, and then you see the boot messages?

Are those reboot msgs really(!) in that order; they show the clock going backwards ... ?

That would be normal for the output of "last"?
