You are right.  I will work with Sangfor to quantify the real impact
in their production scenario -- what DAMOS action is driven by the
inflated hot-memory readings, and how badly the monitoring error
affects the actual outcome.

Thank you, David, and Zi Yan for the honest and constructive feedback.
It made me realize I should have led with the problem, not the
mechanism.

Let me take a step back, gather concrete data on the problem severity,
and come back with a clearer picture.  I will follow up in this thread
once I have something solid to share.

Thanks,
Lian Wang
