[mkgmap-dev] Deathloop on splitting file created by splitter if using argentina.poly --polygon-file

Sat Dec 17 06:30:25 GMT 2022

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)
