[mkgmap-dev] out of memory error

From Carlos Dávila cdavilam at orangecorreo.es on Sun Jul 11 21:15:15 BST 2010

The size of france has increased considerably in the last weeks. I've 
had to increase -Xmx from 1200M to 2000M in a question of few days. I'm 
currently splitting france.osm.bz2 with -Xmx2000M and  --max-nodes=1600000
