It was found that all the flows, including active and inactive, in the config datastore are installed back in switch upon reconnection, as part of the node reconciliation process in OpenDayLight. This may lead to denial of service via table overflow or possibly circumventiagn of controller's control.
Can you please specify how this could cause a DoS? The reconciliation process does push all flows to the switch but it is not additive. After reconciliation the switch will have only the flows that ODL wants it to have and no more. Or am I missing something?

There is currently no resolution upstream and it seems unlikely there will be a resolution. OpenDaylight was technical preview prior to OpenStack 13 and will be deprecated in OpenStack 14.
