Hi:

I am running the latest xen-unstable (otherwise my 32-way machine will
not work ). When I shutdown a domain (sometimes it happens randomly,
but that is very rare) and the domain has more than 512M of ram I get
the following error. Many times I don't need to restart the machine,
but it is acutaly really annoying.

The machine is a 32proc x86-64 machine (hyperthreading is disabled)
with 64 GB of ram

Any ideas?


Thank you,
Pablo.
