Hi Ravi,
I think stonith, implemented in ticket #1859, handles this case. This
"flickering" was one the (manual) tests verifying the added stonith support.
It is important to have a separate interface for stonith, to be able to perform
the remote fencing, similar to use a back plane.
Have you tested with stonith enabled?
/Regards HansN
