While trying to get a new world map update out the door I noticed that Mkgmap sometimes hangs on an OSM data file produced with Splitter. When this happens the CPU is at 100% constantly for hours (e.g. all night) until I kill the process. The problem occurs in r1222 and also r1228. The following command was used for Mkgmap (I know the code-page is redundant): java -Xmx1792M -ea -jar mkgmap.jar --latin1 --code-page=1252 --name-tag-list=name:en,int_name,name --remove-short-arcs --add-pois-to-areas --make-opposite-cycleways --link-pois-to-ways --description='OSM World Routable' --route --series-name='OSM World Routable' Some problematic OSM files are below (created with Splitter r97 and max-nodes=1.200.000): http://planetosm.oxilion.nl/~lambertus/73240155.osm.gz http://planetosm.oxilion.nl/~lambertus/73240185.osm.gz
