001014 : Spatial weights matrices containing over 20 million non-zero links may require a large amount of memory to use.

Description

It is possible, but not advisable, to define the spatial relationships among your features so that each feature has MANY neighbors. This warning indicates the parameters you've selected to create the spatial weights matrix file will result in more than 20 million nonzero neighbor weights. The resultant spatial weights matrix file and memory requirements to create it will be very large.

Solution

You can limit the number of neighbor weights by specifying a nonzero Threshold Distance.
