000718 : <value> polygons had no neighbors based on contiguity; returning neighboring polygon with nearest true centroid.

Description

Island polygons have no contiguous neighbors. To ensure all features have at least one neighbor, the nearest polygon, based on true geometric feature centroids, was used for island polygons.

Solution

This is a good strategy for dealing with island polygons. You might also consider using K Nearest Neighbors or another option for the Conceptualization of Spatial Relationships parameter.
