The warning message is not necessarily an indication of a problem, but it could be useful feedback if you are running into convergence trouble or your surface-based contact results are difficult to interpret.
Attached is a simple example of what would generate this message. In this example, there are two contact pairs that work together successfully in a symmetric contact relationship between areas 6 and 11. There is also a third asymmetric pair that enforces contact between areas 4,6 and 10,11. This is redundant, but it does not cause any convergence difficulty, and it is not a problem if you are not interesting in postprocessing contact-related results on area 6 or 11. If you do want to postprocess contact-pressure results, it might be more difficult to interpret the numbers, hence the warning. In some complicated application, this scenario might be unavoidable.
