It's back up.
Very odd. It has run very stable, with only the one spontaneous system reboot last night at 10:12 PM
Then, tonight, it had another spontaneoud reboot at, you guessed it, 10:12 PM.
That's odd, I thought to myself, and rebooted. Then I went back to getting ready for tonight's DB edits. Then I heard it reboot again!
Not encouragiing. I think I'll go ahead and do a DB clean tonight after I do the edits.
