Timely automatic unexpected reboot on ubuntu desktop

  • 772

We have a remote linux server (ubuntu desktop). The system log indicates the system has been restarted on the timely fashion. Here is a part of the last output:

reboot   system boot  2.6.32-21-generi Mon Nov 19 17:27 - 22:17 (5+04:50)

It looks the system is set to be restarted at 22:17. Can anyone guide me why this happens?

Thanks in advance.

    Look at the day count in the last column.

    The integers before the recognizable time field are days. If you do the math, you'll realize that all those were sessions that were kicked out at the same reboot.
