The problem seems to be in all branches:
In Fluorine it started at around May 23rd so there multiple suspect patches:
https://git.opendaylight.org/gerrit/#/q/branch:stable/fluorine+project:controller
The test itself does:
1) Start a singleton registration flap on every controller instance with this RPC: /restconf/operations/odl-mdsal-lowlevel-control:register-flapping-singleton
2) Maintain the flap for 60 secs.
3) Stop the flap on every controller instance: /restconf/operations/odl-mdsal-lowlevel-control:unregister-flapping-singleton
4) Get flap count from above RPC response: <output xmlns="tag:opendaylight.org,2017:controller:yang:lowlevel:control"><flap-count>83</flap-count></output>
5) Add all the flaps for the 3 controller instances and divide the total by 60 secs.
Before the regression, the controller handled ~50 flaps/sec, after the regression is less than 5 flaps/sec.
