I'm not all that sure it was memory related based on my Sun, 6 Jan
2019 13:17:04 -0600 post.
You'll see the log entries at 3AM, and based on earlier entries I
likely went to sleep around 1AM which would mean any memory intense
applications (eg. virtual machine) would've been closed out.
I have 8GB RAM in my desktop.
