I use a script that re-splits the tile for situations like where Mkgmap 
does not produce a map from initial Splitter results. The script reduces 
node count until splitter produces 2 or more 'sub'tiles, then tries to 
render those subtiles and repeat the process until all subtiles are 
rendered if necessary or until the node count reaches a lower limit.

So the process goes like this:
1- Split your osm.pbf/bz2 file with an initial max-nodes setting (e.g. 
1.2 million)
2- Attempt to render the tiles with Mkgmap into Garmin images
3- See if any of the new Garmin images failed (i.e. do not exist or 0 
bytes in size)
4- Re-split the failed tiles with ever lower max-node counts until 
splitter produces 2 or more subtiles
5- Goto 2 (but render only the subtiles ofcourse)
