[CONTROLLER-872] Flow state not written to node after it is removed and re-added

Thu, 19 Oct 2017 22:13:16 +0000

When flows are written to a node and it offine and returns after a few mins, the flow rules are not written to the node. Even an explicit write does not help.

Here are the flows written to a node on Table #50 before the node goes offline. When the node returns, these rules are not written to the node. Sometimes I see the flow LOADBALANCER_FORWARD_FLOW1_10.0.0.5 being written. Sometimes I see LOADBALANCER_REVERSE_FLOW_10.0.0.5_10.0.0.8 written. It is not deterministic.
