No, there is no limit for the maximum tiles size for now. Thanks for the
hint.
What is the limit? I guess it is not a constant, but depends on
resolution
and other
values? Unfortunately the test data is gone and I didn't download it.
If you want to look at the problem, I can try to regenerate the
data again.
I am not sure if the problem has to be solved in splitter or in mkgmap.
Anyway, please try to reproduce it.
I also like to know why mkgmap has problems with tiles that contain only
very few nodes. Or is it the gps device that has problems?

I played a little bit with a small testfile how large a tile can be. The
attached test file has the maximum size which works for me:
<bounds minlat="0.0" minlon="0.0" maxlat="85.0" maxlon="179.98"/>
Larger bounds cannot be put into a single tile.
For large tiles mkgmap requires much memory problem if the bounds
parameter is set. They need to be completely loaded with a high memory
consumption.
I don't know if there is a hard limit for the tile bounds size. Maybe
using some limits in splitter for the maximum latitude and maximum
longitude size would remove some problems, e.g. max lat = 20, max long = 20.
