This normally is more of an informational message on the Nexus 5k rather than a hardware/software issue. All this message is telling you is the switch is seeing MAC addresses move between different interfaces in the same VLAN at a rapid rate. To protect the CPU dynamic learning is disabled for 3 minutes when this condition is met.
In newer code, we would also print a message with actual MAC address moving and interfaces they are moving between.
In most cases, in my experience this occurs during
1)A Bridging loop
2)A misconfigured device. For example if you connect a server which has teaming configured but do not configuring the switch interfaces to be in a etherchannel, the switch would see same MAC addresses on both interfaces.
