The Question is:
What are possible causes of an Alpha server rebooting? If there detail logged
anywhere as to what may have cause a reboot?
The Answer is :
The list of things that can cause a reboot is an open-ended set.
The usual (and best) spot is the console output around the time
of the reboot -- certain operations normally write log entries,
but you likely would have already found and seen these entries
were this a normal case. In particular, you will want to channel
console output to a log file or to a printer.
