Here you go, for this error to go away i.e. in Switzerland I had to 
reduce maxnodes to 200.000:
start /low /b /wait java -jar -ea -Xmx2600M mkgmap.jar --max-jobs=3 
--latin1 --ignore-maxspeeds --ignore-turn-restrictions 
--remove-short-arcs=5 --road-name-pois=0x2f2d --add-pois-to-areas 
--location-autofill=1 --description=openmtbmap_%abr%_%date% --route 
--country-abbr=%abr% --style-file=new2 --country-name=%country% 
--mapname=%mapid%0000 --family-id=%mapid% --product-id=1 
--series-name=openmtbmap_%abr%_%date% --family-name=mtbmap_%abr%_%date%  
--tdbfile --overview-mapname=mapset00 --keep-going %mapid%00*.osm.gz

gives me:
