See the message I just now posted to xen-devel about NFS root hangs; could this be what we're hitting? The most recent hang we saw happened while an rsync was running over ssh *and* someone restarted apache... This wouldn't cause the "NFS server not responding/NFS server OK" messages on the domain's console, though (or does that show up as a symptom of this too?)
