I have run several times splitter on a 15.1 GB file (actually on cache
from that file) obtained from Srtm2OSM on machine A (Athlon 64 3000 Ghz,
3GB RAM) using the following command:
time java -Xmx2500M -jar splitter.jar --mapid=63240101 --mixed=true
--cache=/160GB/cache_srtm/peninsula/ --max-nodes=4500000
--split-file=areas.list --description="SRTM Map" --overlap=1000
Running the same command on the same data on a new machine B (Athlon II
3000 Ghz dual core, 4GB RAM) I get an OutOfMemoryError. Even increasing
to -Xmx3500M I get the same error, always at the same point.
Running mkgmap on spain.osm from Geofabrik with my usual script I also
had to increase memory.
Machine A java -version:

Any ideas about the problem?
Carlos
P.S. Does it make sense to give --overlap to splitter for contour lines
or is it only necessary for routing?
