Hi Shuva,
The FLOW_REM flag been set on the flow(table=46). I see this functionality been broken in stable/carbon too(as I see stable table=44 entries in CSIT run).

NAT has implemented SalFlowListener and does certain clean-up on receiving Flow Removed Notification on specific table(on IDLE_TIME_OUT). public class NaptFlowRemovedEventHandler implements SalFlowListener { public void onFlowRemoved(FlowRemoved flowRemoved) { ... } } As a result of onFlowremoved() not called, certain allocated ports where never released(allocated for an SNAT session) and certain flows(table=44) where never gets removed from Switch. I see the following flag been set to true(ODL-master\netvirt\vpnservice\distribution\karaf\target\assembly\system\org\opendaylight\openflowplugin\openflowplugin-blueprint-config\0.5.0-SNAPSHOT\openflowplugin-blueprint-config-0.5.0-SNAPSHOT-config.cfg) #Flow removed notification is turned on by default. Default value true enable-flow-removed-notification=true I have opened a bug to track this issue. https://bugs.opendaylight.org/show_bug.cgi?id=8238 Request to let us know on this issue.
