I am trying to do a very basic summarize within function using hex bin polygons and around 40,000 points. The tool fails with a generic 999999 error which leaves me completely baffled with no direction to troubleshoot. Both data sources are wgs84 and are sitting in the same gdb. I tried to keep it as simple as possible and have it summarizing 0 or 1 field at most. Any ideas on how I can troubleshoot? Thanks.
