This is unlikely to have anything to do with networking or
multicast. Xen's per-page reference counts ahve got out of sync, such
that a page has ended up freed whil eit still has a non-zeo 'type
count'. This may be related to the crashes doing decrease_reservation
in the net frontend driver. Look slike at least on epage-management
bug lives on... :-(
