There's nothing the least bit suspicious in the logs you gave. It was
probably just a power outage. Do you have any reason to believe it
was something else?

If you really want to know what caused them...

Cron ran four jobs as root because:
1. You have "atsar" installed. I've never used it, but judging from
the package description, it's no surprise that it runs
periodically to collect system performance information.
2. You have a custom Exim installion. The above line is the usual,
periodic queue run to retry sending messages that have temporary
delivery failures.

These lines are inserted by "syslogd". It's just to ensure a regular
message gets written to "messages".

These are normal. Cron generates these messages when it's running
jobs as root. These specific messages correspond to cron running the
"atsar" and Exim cron jobs mentioned above.
