Frequent label change events for a host machine(s)

Problem:

I am getting frequent change events as below for a host machine but we haven't made any changes on our side. Why Instana is detecting these below change events?:

The value label has changed from "X" to "Y".

Solution:

This situation could arise if you have assigned the same MAC Address to two or more machines. Assigning a unique MAC Address should resolve the issue and Instana will no longer trigger these label change events.
