Gianni,

I guess it's possible that the core auto rebooted, but I have not rebooted it in weeks.
It's been my experience that it only reboots after a Sooloos software update, and we have not seen one of those in some time.

I am running the core on the MD600. The C15 has always been used as a control point.
