I think this is the problem here too. Over Christmas I downloaded the
opensuse KOTD, hoping that it maybe fixes the problem. the dom0 was
disconnected from network, and I had two domU's running, and I copied a 650
MB file between these two via scp, for thousand times.
Two days ago, I connected the dom0 to the network again, and started using
the domU's as file/print/... servers again.
It took about an hour, and the server was frozen again, without any notice
in /var/log/messages.
I created a bugreport, maybe you can add your observations there too.

I use dom0_mem, yes, but with and without this parameter, in both cases the
dom0 froze.
