One of my servers this morning shut down and I don't see any cause for it.  Messages contained:

Jul  1 00:00:00 master newsyslog[14835]: logfile turned over
Jul  1 09:45:54 master nrpe[1229]: Caught SIGTERM - shutting down...
Jul  1 09:45:54 master nrpe[1229]: Daemon shutdown
Jul  1 09:45:54 master ntpd[1159]: ntpd exiting on signal 15 (Terminated)
Jul  1 09:45:55 master kernel: .
Jul  1 09:45:55 master syslogd: last message repeated 1 times
Jul  1 09:45:55 master syslogd: exiting on signal 15

console.log showed a bunch of daemon shutdown messages followed by:

Jul  1 09:45:55 master kernel: Writing early boot entropy file: .

Usually with a power problem there is nothing until the system is started back up.  Here I got a few messages that something initiated the normal shutdown but didn't leave any record.  Any way to figure out what caused this?

None of my other servers had any issues.
