Web Server Bogged Down

     Something put a high load on the web server this morning to the point where I was unable to login and even investigate.  Upon rebooting operation returned to normal.

     The fact that this happened on a Saturday just like after I upgraded to Ubuntu 16.04, and at about the same time, has me wondering now if the same thing that happened today didn’t happen then and it wasn’t just coincidence that I had upgraded to 16.04.
