NGA Geonames Gazetteer - Locator

[StephenRoberts]

Hi, I am trying to create and publish a NGA Gazetteer using this workflow (Geonames Locator | ArcGIS Solutions for Defense). When I run the "Create Geonames Gazetteer" model it runs for a few hrs and always fails at Building Suggestions index. I have to check "Enable Suggestions" for the end service to work properly. Does anyone have any clues as to why Building the suggestion index might fail? 

I'm using the NGA Country files for input. (NGA: GNS Download Country Files )
