First, this is *very* bad - I'm not good enough on this to tell you if
it's the CPU, or the motherboard, but it's one of the two, *not* just
memory. Second, if you're paying for hosting, and it's *their* server, you
need to get on the phone with them *now*, and tell them that they need to
fix it, yesterday would be preferable. They *should* have seen the logs.
Dunno if you have a physical machine hosted there, or a VM' if the latter,
they can move it without you seeing any downtime at all. If the former,
they can just hot swap the drives into another server.
But call them *NOW*. You're paying for the service.
