[OVSDB-237] Security group : default ip flows fails to delete intermittently

Thu, 3 May 2018 14:37:00 +0000

When terminating an instance, the default ip flows fails to get deleted from the flow table. This happens intermittently and not always.

Steps to recreate:
1) Spawn a VM with the default security group.
2) Verify that the ip flows are seen
3) Now terminate the instance or disassociate the default SG from the VM
3) Verify the flows are deleted.
