Hi All,

My goodness!  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?)
