Thanks Ticker!

I reworked my wrapper script so splitter and mkgmap save their
output separately and now I can see that this message was actually
from mkgmap, not splitter, and see that this was the cause:
SEVERE (MapFailedException): /u/ahux/tmp-dir/as/85120555.osm.pbf:
(thrown in RoadDef.writeRgnOffsets()) Overflow of the NET1. The tile
(/u/ahux/tmp-dir/as/85120555.osm.pbf) must be split so that there are fewer
roads in it
so I followed your advice:
> you need to experiment with splitter max-nodes to fix this
and halved max-nodes to 800000 and Asia now works!
I'm processing all continents every three months [*]; is there any
disadvantage if I lower max-nodes for *all* continents, rather than
just the problematic ones? (I'm thinking about my wrapper scripts.)
I'll regenerate the other continents anyway, to check if there
are any obvious problems and also to see how the execution time
compares to before. So far my record for Europe is 03:02:31 for
splitter/mkgmap/zip :-)

All your suggestions applied.
Thanks again!
