So, I can run about 5 consecutive processes for a spatial join before Wing crashes and processes no more. Using a Point and a Poly layer to Join. Point layer is 774,796 records. Poly layers vary, but are much smaller than point. Spatial Join in a list, which makes this a tedious process in that I get to wait for the crash and then remove the layer from the list and then reprocess the list, so it kinda makes using lists not optimal. Physical Memory drops to about 34,000 K before the crash. It steadily goes down from the first to the sixth layer, with the sixth layer not completing successfully.
Good Times.
oh, this is running in a File GDB.
There is NO error number generated, it just stops. Believe it is runaway memory.
