I got two series of notifications in an email from my server that I've never seen before, don't understand, and that worry me a bit.
The first I found in /var/log/system:
I've seen these kinds of messages frequently when it's reporting on other devices in the network, especially when I have my laptop on both WiFi and ethernet. But this IP address is the server itself. There's only one ethernet cable going in. And it switches one way and doesn't switch back. Puzzles me.
The second is maybe more concerning because it suggests some kind of memory error, but looks like the CPU rathern than RAM? From /var/log/messages:
What do these mean? Should I be concerned?
