Hi Jozef, More observations:
I've retested bug 7462 (OVS restart scenario) using the master branch with the latest patch revisions (including patch 51676 and 51500) and found that 7462 is once again reproducible. When restarting openvswitch, if the master remains the same ODL node, the pipeline flows are pushed down successfully. However, if the master switches to a different ODL node, the pipeline flows are not pushed down and it appears that the previous workaround of inserting a short delay between 'start openvswitch' and 'stop openvswitch' does not work. I've tested with a delay of 20 seconds between stopping and starting openvswitch. If I don't include the 51676 patch in the my deployment, now the master doesn't change, but 7462 is intermittently reproduced but the difference is that while most of the time the pipeline flows are successfully pushed to the device, sometimes only some of the pipeline flows are pushed (~10% of the time), while at other times none are pushed at all (< 5% of the time). I'll do more testing and let you know if I find anything else.

To reproduce: 1) connect switch to all instances: sudo ovs-vsctl set-controller s1 "tcp:192.168.0.101:6633" "tcp:192.168.0.102:6633" "tcp:192.168.0.103:6633" 2) use sudo ovs-vsctl list Controller to determine master instance (e.g. 101 above) 3) disconnect a candidate (103 above): sudo ovs-vsctl set-controller s1 "tcp:192.168.0.101:6633" "tcp:192.168.0.102:6633" After that I see the following in karaf log of the candidate: 2017-02-10 03:01:19,830 | INFO | entLoopGroup-7-1 | SystemNotificationsListenerImpl | 227 - org.opendaylight.openflowplugin.impl - 0.4.0.SNAPSHOT | ConnectionEvent: Connection closed by device, Device:/192.168.0.24:59753, NodeId:openflow:1 2017-02-10 03:01:19,832 | INFO | entLoopGroup-7-1 | ContextChainHolderImpl | 227 - org.opendaylight.openflowplugin.impl - 0.4.0.SNAPSHOT | Device openflow:1 disconnected. 2017-02-10 03:01:19,832 | INFO | entLoopGroup-7-1 | ContextChainHolderImpl | 227 - org.opendaylight.openflowplugin.impl - 0.4.0.SNAPSHOT | Context chain for device openflow:1 successfully stopped 2017-02-10 03:01:20,838 | INFO | pool-31-thread-1 | ContextChainHolderImpl | 227 - org.opendaylight.openflowplugin.impl - 0.4.0.SNAPSHOT | Removing device: openflow:1 from DS As a result of candidate clearing the DS, the master gets all kind of exceptions and switch cannot connect anymore to controller. Workaround: restart cluster. Conclusion: the patch creates regression.
