The first crash since the extra RAM and h/drive were added. No clue just yet.
The system went down just after 20:24 local time, and returned at 21:33, which was over 5 minutes after I rebooted the machine. I took the time to take the Qube apart and plug the internal fan back in, as some of the chips were too hot to touch comfortably – perhaps it’s time to move the server out of the loft for the summer.
Annoyingly, I hadn’t bargained on the time it would take to reboot with a drive of this size, so I was very nearly about to take it back down again to move it closer to a debug machine with a serial port. Still, the soft deps. are on my side, even if the rest of the stuff is conspiring. I’ll keep digging, in the hopes that the cause might come to light.
