Hi Oliver!

I have a triangle shaped network topology of 3 ovs 1.4.1
switches. When I plug-in a host into the network I immediatly
start to observe the same log pollution and excessive CPU usage
similar to yours. I either need to un-plug the machine or break
the triangle into a straight line by removing one of the
connections between the switches. Have you made any progress on
your side about the problem? Any clues?

Try enabling the STP (spanning tree) the traffic might be getting looped causing high load.
