Description (partial)

Very occasionally, with odds increasing towards moderate to high level of mac-address table utilization, port security (on a random port) might exhibit symptoms that host behind secured port does not receive any traffic (except local CPU outbound traffic)

This problem exposure is related to the dynamic picture of utilization of mac-address table and odds of used mac-address table distribution. It's impossible to predict whether certain combination of MACs/Ports/vlns would to prone to this problem or not.
