[mkgmap-dev] splitter r279

I have tried to split a large part of Western Europe (6 Gb) on a modest laptop (Win32, java -Xmx1400m) and after several hours the splitting process is stopped: 

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
	at uk.me.parabola.splitter.MultiTileProcessor.endMap(MultiTileProcessor.java:247)
	at uk.me.parabola.splitter.Main.processMap(Main.java:817)
	at uk.me.parabola.splitter.Main.writeAreas(Main.java:705)
	at uk.me.parabola.splitter.Main.split(Main.java:250)
	at uk.me.parabola.splitter.Main.start(Main.java:156)
	at uk.me.parabola.splitter.Main.main(Main.java:145)

I couldnt see when it happened, I guess it was after the splitting process has done several sections (8/8).
There wasn't any osm.pbf file produced, only densities-out.txt, areas.list and areas.poly.

java -Xmx1400m -jar %SPLITTER% --output-dir=splitter --polygon-file=w-eu2.poly --keep-complete --overlap=0 --max-areas=100 --mapid=97810001 --max-nodes=1400000 --write-kml=%areas%.kml --output=pbf --geonames-file=cities5000.txt --description=OFM_EU w-eu.osm.pbf 2>log.txt

The w-eu.osm.pbf extract is a combined file with osm data (Benelux, Germany, Switzerland, France, Northern  Italy and Northern Spain) and contour lines.

I had no problems with a Germany extract or another Europe extract (the input files were .05m format though, will this consume less memory?). I could try to split the extract in 05m instead of osm.pbf. What other options can I try, higher than 1400m is no option, java wouldnt run. Or a lower value of max-areas?
