Hi, I tried resplitting a file that was too big for the map creation using splitter - and if I use the boundary file splitter.jar is getting stuck finding a solution (until killed). Command: start /belownormal /b /wait java -XX:+AggressiveHeap -Xms5000M -Xmx40000m -jar C:\openmtbmap\splitter.jar --max-nodes=1400000 --output=o5m --geonames-file=E:\openmtbmap\osmpbf_geofabrik\cities5000.zip --polygon-file=E:\OpenMTBMap\osmpbf_geofabrik\argentina.poly --description=argentina --mapid=64700017 "64700010.o5m" If leaving out the polygon-file it works without problems to resplit it again. Command used to create the file that fails to be splitted again: C:\openmtbmap\splitter.jar "--precomp-sea=E:\OpenMTBMap\osmpbf_geofabrik\sea.zip" --polygon-file=E:\OpenMTBMap\osmpbf_geofabrik\argentina.poly --max-nodes=2800000 --max-threads=11 --search-limit=1000000 --output=o5m "--keep-complete" --route-rel-values=mtb,bicycle,foot,hiking,road,mountainbike,ferry,shuttle_train,subway,train,tram,river,canal,ski,piste,walking --max-areas=4000 --geonames-file=E:\OpenMTBMap\osmpbf_geofabrik\cities5000.zip --description=argentina --mapid=64700000 E:\OpenMTBMap\osmpbf_geofabrik\argentina.o5m 1>NUL However I also uploaded the file for debug: https://openmtbmap.org/64700010.o5m I don't think there is a problem in general with splitting a file splitted by spliter.jar again using smaller max-nodes and using polygon-file option. Something is special here that it fails (happened already one week ago with a 7 day older geofabrik extract) -- Felix Hartman - Outdoormaps LTD - Openmtbmap.org & VeloMap.org
