1) Node A sends prepare message (msg1) to Node A 2) Node B sends prepare message (msg2) back to Node A 3) Node A prepares what to receive according to msg2 The issue is that, Node B might sends before Node A prepares to receive. To fix, we send a PREPARE_DONE_MESSAGE after step 3 to notify node B to start sending.
