Hi Shuva The failures are seen in 2 scenarios.
Scenario1 ========= - It's a 3 node cluster ( leader , follower1, follower2) - Start Mininet Connect To Follower Node1, connect 3 DPNs to it - 3000 Flows (1K per DPN) in 3 DPN added via Follower Node1 and verify it gets applied in all instances. - Initiate (Bulkomatic) get operation and check flow count across cluster nodes in config DS - Verify flows are installed in switches , the test fails here ( flow seen in 2 DPN not in 3) Scenario2 ========= - It's a 3 node cluster ( leader , follower1, follower2) - Shutdown Leader Node - Wait for node convergence and check status for all shards in OpenFlow application - Start mininet with connection to Follower Node1 ( 1DPN) - 1000 Flows added via Follower Node1 and verify it gets applied in all instances (config DS). - Verify flows are installed in switch, the test fails here, no flow seen in the DPN However I see flow installation in normal 1K flow -1DPN works fine in regression. Please let me know if any more clarification needed.

Since in case case I see s1 not getting flows(strangely). S2 and s3 gets them. Can we run the failing TCs alone without the suite ?

Also do you see the flows in the inventory config DS ?

Sanjib, can you also add exact steps to reproduce in the bug? Thanks/Luis
