FreeBSD-7 reboots hourly

[Johan Hendriks]

>Hello dear colleagues.

>2 days I have strange behaviour on my 7.0-RELEASE-p3 server.
>It started to reboot once an hour.
>No any suspicious task in crontab, nothing strange in /var/log.
>Just silent reboot.
>I have no physical access to server - only remote one.

>Question is: what could it be?
>How to find what send computer to reboot?

Try to disable some cronjobs that run hourly.
