[OPNFLWPLUG-686] Li-Plugin: Transaction failure exception in 3-node cluster while processing port statistics

Duplicate — Mon, 27 Sep 2021 09:01:48 +0000

I am testing net-virt with openflowplugin lithium plugin in 3-node cluster environment. Whenever OVSDB connects to net-virt, it creates the bridge and set the controller of the bridge to all the three controllers in the 3-node cluster. Whichever instance of openflowplugin become the owner of the openflow bridge, it starts throwing following exception while processing the port statisitics
