Geofabrik's daily 'asia-latest.osm.pbf' has this problem. I just re-downloaded
from http://download.geofabrik.de/asia-latest.osm.pbf to verify the problem 
is still there, which it is. In case it helps, the checksum of the 
asia-latest.osm.pbf I just tested is:

	$ md5sum download-cache-dir/asia-latest.osm.pbf 
	bae4ea71f6b48366cb21c2cdf5ceda20  download-cache-dir/asia-latest.osm.pbf
	$

Besides the numerous 'Tile contains both drive-on-left and drive-on-right'
messages, which is what I originally posted about, and  which Ticker has 
already explained are not really errors, these are the other errors:

	$ grep SEVERE *.log | grep -v 'Tile contains both drive-on-left'
	SEVERE (RestrictionRelation): 59890171.osm.pbf: Turn restriction (only_straight_on) http://www.openstreetmap.org/relation/9335096 (at http://www.openstreetmap.org/?mlat=-6.442483&mlon=106.830079&zoom=17) via node is not a routing node
	SEVERE (MapFailedException): 59890543.osm.pbf: (thrown in RoadDef.writeRgnOffsets()) Overflow of the NET1. The tile (59890543.osm.pbf) must be split so that there are fewer roads in it
	SEVERE (MapFailedException): 59890570.osm.pbf: (thrown in RoadDef.writeRgnOffsets()) Overflow of the NET1. The tile (59890570.osm.pbf) must be split so that there are fewer roads in it
	$

For the 'Overflow' ones, Ticker already advised me how to split the tiles
up a bit more.

Regading the 'Turn restriction', I've copied the specific tile 59890171.osm.pbf 
to https://datashare.rzg.mpg.de/s/RHEzSLYhNNkPbfb?path=%2Ftmp. 

My splitter and mkgmap command line arguments are:

	java -Xmx380000M -jar splitter.jar --mapid=59890001 --search-limit=1000000 /u/ahux/tmp-dir/as/asia-latest.osm.pbf
	java -Xmx380000M -jar mkgmap.jar --code-page=1252 --latin1 --route --remove-short-arcs --add-pois-to-areas --index --location-autofill=is_in,nearest --tdbfile --mapname=59890001 --family-id=5989 --family-name="OSM_AS" --overview-mapname=as --series-name="OSM Asia (2019 08)" --description="OSM_AS" --bounds=/u/ahux/tmp-dir/as/bounds-latest.zip --precomp-sea=/u/ahux/tmp-dir/as/sea-latest.zip --style-file=/u/ahux/tmp-dir/as/mkgmap/distrib/mkgmap-r4287/examples/styles/default -c template.args

and I'm using:

	$ ls -l ../../download-cache-dir/*.zip
	-rw-r--r-- 2 ahux rzs 1090392991 Aug  1 10:36 ../../download-cache-dir/bounds-latest.zip
	-rw-r--r-- 1 ahux rzs    3401612 Aug  1 11:45 ../../download-cache-dir/mkgmap-r4287.zip
	-rw-r--r-- 2 ahux rzs  224903148 Aug  1 10:36 ../../download-cache-dir/sea-latest.zip
	-rw-r--r-- 1 ahux rzs    1569564 Aug  1 11:45 ../../download-cache-dir/splitter-r592.zip
	$

Hope that helps you to help us! :-) Thanks!
