[ovs-discuss] Locating the Source of a Flood Storm

In a custom network created using mininet, I quite often (but at the same
time randomly) find ovs-vswitchd using 100% of the CPU. And due to the
excessive CPU usage, even PacketIns cannot make their way to the controller
and consequently controller cannot perform any forwarding or management at
all. I suspect a flood storm in the network, but I am having trouble in
coming up with a practical method to figure out the problem. Any ideas?
Where should I start checking? Is there any configurations in OVS that I
can make it to report me the *problematic* flows? I need some guidance and
