-------------------
And the shell I had a "top" running in on xwindow #2 had crashed with a SIGABRT.
This was about 10 minutes after I had gone out to make some more cement blocks,
which takes around 3 hours.

I was able to restart the shell, and the top. The system "feels" normal.

I'm going to call tcwo tomorrow and see what I can get in new hardware.
This is fscking ridiculous. I get a cpu/cooler/fan that runs 40C
cooler than the old one and its doing nothing but crashing. The
absolute longest uptime so far was the recent nearly 37 hours.
