Patrick, blackbox may be useful. Also log may help us trace what happened. This looks like some kind of problem when corosync nodes split and then join again... anyway, it's weird and looks like a bug. Another helpful thing may be coredump of corosync from affected node (so 10.20.0.127) to ensure it is not memory corruption problem.
