Last night at 23:53 my server rebooted. Looking in the logs, there is nothing to suggest any problems or processes trying the reboot, although the actual restart is logged in /var/log/messages ( May 30 23:54:30 starbug syslogd 1.4.1: restart. ).
I'm really confused about this though. From typing "last", I see that the kernel logged in as a user called "reboot" at the same time my server restarted - or at least this is what it looks like
bigwheel pts/0 adsl-83-100-180- Tue May 31 10:13 still logged in
reboot system boot 2.6.9-5.0.5.EL Mon May 30 23:53 (10:25)
bigwheel pts/0 adsl-83-100-133- Mon May 30 13:47 - 20:12 (06:24)
bigwheel pts/0 adsl-83-100-162- Sun May 29 13:18 - 20:46 (07:27)
This has also happened once before, awhile ago. Anyone got any ideas on what's going on?
I think Shockuk is trying to figure out why it rebooted. The reboot entry in "last" just shows that the server was rebooted, but a user "reboot" didn't log in or anything. It's probably a reboot done by your datacenter or something, since no user was logged on when the system rebooted.
