What caused this shutdown/reboot?

[Janos Dohanics]

Hello All,

This is a FreeBSD 9.2-STABLE #0 r265089 amd64 box.

I have these entries in /var/log/messages:

Sep  3 15:18:51 dutchman kernel: .
Sep  3 15:18:52 dutchman kernel: , 690.
Sep  3 15:18:52 dutchman kernel: .
Sep  3 15:18:53 dutchman kernel: , 602.

Meanwhile, in /var/log/apcupsd.events:

2014-09-03 15:18:52 -0400  apcupsd exiting, signal 15
2014-09-03 15:18:52 -0400  apcupsd shutdown succeeded
2014-09-03 15:23:06 -0400  apcupsd 3.14.10 (13 September 2011) freebsd startup succeeded

Do I have a flaky UPS or was this some mysterious process that shut
down/rebooted the server?
