unfortunately the splitter does not seem to offer that option, it seems
that one can only limit the number of nodes.

but your diagnosis looks rather likely: i've counted the number of ways
in the tiles:

% for f in *.osm.gz; do echo -n "$f ";zcat $f|egrep '^<way'|wc -l;done

with your changed assertion output...

java.lang.AssertionError: NET 1 offset too large at (http://www.openstreetmap.org/browse/way/6926238)

(a pretty short way, btw, just five nodes)
...it was easy to find the problematic tile:

% zegrep "^<way id='6926238'" *.osm.gz
63250389.osm.gz:<way id='6926238'>

it's the tile with 220462 ways!
