Server is back up and running. I'm not sure exactly what happened, but somehow it shut itself down? It looked like someone had actually stopped it from the console around 3:40 am, rather than crashing... but unless the ghosts here know how to do that, .... Never seen that happen before!
The upside, everything prior to the shutdown should have been saved!
Glad you guys posted it on here, otherwise may have been a while yet before I would have found out about it!!
