Say an accidental quick push on power button or - humor me - the cleaning lady is with the conserve energy movement and thought your box just another forgotten-to-shutdown desktop, that alone could explain your mysterious shutdown incident. The machine is located in a server room within a server rack with a (detachable) panel on the front side of the machine (Dell Poweredge) that is covering the power-off button. No cleaning lady is entering the room, especially at 3 AM. Due to all the circumstances I had described, I ruled out (physical) human factor as the cause of shutdown. The box has two independent AC power supplies, no hardware error is found in RAC card logs, no other server (in the same rack/room) shut down at that time. That is what leads me to believe that the problem is software-related. I know there are many possibilities out there, but I am pondering this for the whole day and ruled out everything that came to mind. So, any other ideas - even humorous - are welcome. Thanks for the input in any case. Regards, -- Nino
