I have tried to reproduce your issue but was unsuccessful. Could you help
narrowing down the cause by providing some more information ?
For instance:
* What is the simpliest setup that can provoke the issue ? Does it also happen
if you only involve 2 nodes ? Or 3 / 4 / 5 ? Does the problem go away if you
reduce the number of interfaces on each node ?
* You provided some logs showing additions / deletions of a non-existing mac
address and you said this would go away after a while. What do the logs say
when the problem is about to disappear ?
* Are the nodes that often exhibit this flakiness far apart or direct
neighbors ? What does the topology look like ? Again, the simplier the setup
the better.
