Periodic reboots

I have what is to me a unique and strange problem. After just over 2 years of up time I rebooted my Sun Netra X1. Since that reboot it has been, as near as I can tell, resetting itself approximately every 11 hours and 42 minutes.

I have syslog logging *.debug but I don't see any hints there....actually I don't see anything abnormal. Just a normal log message, then the boot information. I've tried capturing packets and there is no pattern there that I can see either.

I've also pretty much disabled every cron job such that only ones I know have never given me a problem are running.

Any ideas what is going on or clues where I can look to figure it out?

Thanks in advance.

This may be totally unrelated, but I had a similar problem a couple of years ago. We had several systems that just booted on their own. It turned out to be power management. Make sure its set for noshutdown. No harm in checking.

Great idea. I don't think I considered this before. But unfortunately this isn't the root cause. I looked intothis and a) I don't have a power.conf file and b) the power daemon isn't enabled to enforce this.

I really wish this solved my proble. Thanks anyway.

Since I was near the server co-lo today I did a controlled halt and while at the OK prompt I reset everything to the defaults and did a boot -r just to be thorough. Maybe I'll be lucky and that will solve the problem.

Put something to capture console output, not all hardware problems get captured in the syslog.. .7/M.

Just to follow-up on my problem. I was able to swap hardware (well the system unit only) with a spare I had available. This solved the problem of the periodic reboots. Since I kept the same HDs with the new hardware and the same memory from the problem machine it would seem to indicate that the OS was not the problem nor was the memory.

However as a twist I now have the problem machine at home. It has been up and running with no reboots for over 4 and a half days as of the time of this posting.

So in conclusion, I have no idea why the machine was rebooting, unless it was a combination of the OS with the old hardware.
