It seems that my server keeps restarting. I want to know why.
How can I know when the last time server was rebooted and why?

In Linux is there ANY WAY to know why the system rebooted? Specifically did high load cause it? If not that then What?
Best Answer
That is the main log file you should check for messages related to this. Additionally either
/var/log/syslog(Ubuntu) or/var/log/secure(CentOS)To find out when your server was last rebooted just type
uptimeto see how long it has been up.
