It was nice to wake up to so many blocks.  

It was not nice to wake up to the the VM that runs my node and rental bot being nearly down and completely useless.  It was completely out of memory.  It was up but unusable, yet it was not so unusable as to set off my alarm during the night.  Although it has worked perfectly for months now, starting last night a grep command in a script I had monitoring the node started thinking that debug.log was a binary file instead of a text file (throwing a "Binary file (standard input) matches" error) and somehow that led to a memory leak down the line (I still don't know exactly how).  Rebooting and adding a -a switch to the grep command fixed it, but along with the node my rental bot was down much of the night.  

Then, just as I fixed that the power went out for about an hour!  When the power came back on none of my A6 would mine.  I had to reflash the SD cards and reconfigure to get each of the rPi to boot.

Crazy morning!
