Hi guys,

My SLES 11SP3 server randomly reboots and i cannot find anything in the logs

last

root pts/0 10.16.56.1 Mon Apr 22 19:17 still logged in
root pts/1 :0.0 Mon Apr 22 18:44 - 19:15 (00:30)
root :0 console Mon Apr 22 18:43 - 19:15 (00:31)
root :0 Mon Apr 22 18:43 - 18:43 (00:00)
root tty7 :0 Mon Apr 22 18:43 - 19:15 (00:31)
root pts/0 10.16.56.1 Mon Apr 22 18:25 - 18:47 (00:22)
reboot system boot 3.0.101-0.47.71- Mon Apr 22 15:45 (03:31)
root pts/0 10.16.56.1 Thu Apr 18 05:53 - 06:03 (00:10)
root pts/0 :0.0 Wed Apr 17 13:16 - 13:18 (00:02)
root :0 console Wed Apr 17 12:51 - 13:18 (00:27)

I know if a user involves a reboot it is logged like this

reboot system boot 3.0.76-0.11-defa Tue Nov 27 09:49 (00:-22)
root pts/1 10.16.56.1 Tue Nov 27 09:05 - down (00:41)

Please, any help would be appreciated

Thank you

Hi,

is there anything suspicious in syslog around the time of the reboot? If there’s no user to blame then I would suspect something relevant in /var/log/messages.
