[pajarraco]

I have couple of days with ubuntu, I install server 7.10 and i configure LAMP and Darwin Streaming Server, everything work fine but my machine is reboot it unexpectable.

When I working with it is fine, but when I leave it along thru the night, in the morning. I found that it was rebooting all night.

I don’t get any error message

If anybody have the same problem?
please I need some help or if somebody can tell me How can I see what is the problem?

What do your logs (/var/log/syslog in particular) say around the time of the reboot?

You're not falling for the common syslogd 1.4.1#17ubuntu7: restart confusion where it's actually syslogd restarting (to roll the logs) and not the server itself?

I not sure if the hardware has problems because i had windows server installed before and never reboot.

I'm going to check the log. I let you know

Thanks.
