Anyone seen unicast flooding but the destination MAC is in the CAM table?

This is from some catalyst switches, I've confirmed the unicast flooded traffic's MAC destination is in the CAM table. Storm-control is triggering ingress from the access ports. I know what the common solutions are to this, but I am finding a hard time understanding why it's happening if the MAC is there in the table to forward it up. TCAM utilization is fine.
