Siri,

For further clarification I should add that the node pairs need to 
know about each other because they use distributed mnesia.  The node
pairs which may run an instance of an application each maintain a copy
of the mnesia tables which they need to run.  If serverA fails node2
will take over it's app1 instance and continue operation with the current
tables.  The problem comes in with the fact that the active nodes all
use mnesia distribution and pg2 betwen them (e.g. node & node4) as well.
