This was brought to my attention because one program was killed by the
kernel to free memory and another program failed because it was unable
to allocate enough memory.

Right, and that website says that you should look at the "available"
number in the results from "free", which I what I was referencing. They

available. Mine was down to 17% in what I posted in my email and it was
at about 8% when I rebooted yesterday.
