I'm getting something weird as well. Wonder if it's a hardware issue bubbling up. For years on this system I've had an average CPU load hovering just over zero, and since the last reboot I've been getting 2+ all day long (it's a quad core Haswell with only around 50 devices). FYI the reason I rebooted was I was getting WAN disconnect/reconnects.
Here is the last week - any thoughts? Nothing has changed.
