Choropleth: Failed to memory map index files

Builder

Hi splunkers!
While trying to add KMZ file to use awesome choropleth map with my country I got this error:
Failed to memory map index files.

Here is a piece of search.log:

Our file is in kmz, it contains filled Name param (featureid).
Search string that I used:

source=purchases | geoip ip_address | lookup ru_regions longitude as ip_address_longitude, latitude as ip_address_latitude | stats count by featureId | geom ru_regions

Link for downloading kmz file:
http://gis-lab.info/data/rusbounds-rosreestr/regions2010_wgs.kmz
Test geodata:
test_data.csv
Hope for your help, I want this cool viz so much:)

I am like 99.999% sure its the KML that you are using.

The regions that you have defined are not unique... therefore when there is a mapping from splunk onto the geom it is confused on which area you are talking about.

Just a quick look at your KMZ shows that you have a lot of "avtocod" that are named the same (e.g. 87, 29) and that is the default featureId that you are using. The only reason I know this is because I just had the same issue.

Try using "/Placemark/region" as your Feature Id Element.

Thanks for your answer! Unfortunately changing feature id element name in lookup definition didn't help( I attached sample geodata in csv, maybe it can help.
