Just these, which were previously present: /-------- | SEVERE (StyledConverter): Way Rosscoff - Cork (OSM id 27279778) contains a segment that is longer than 16383 (routing will fail for that way) | SEVERE (StyledConverter): Way Rosslare - Cherbourg by IrishFerries.com (OSM id 33408220) contains a segment that is longer than 16383 (routing will fail for that way) | SEVERE (StyledConverter): Way Rosslare - Cherbourg by IrishFerries.com (OSM id 33408221) contains a segment that is longer than 16383 (routing will fail for that way) \-------- Also, I forgot to mention that mkgmap hangs after the exception, rather than exiting with an error. Thanks for looking into it. FWIW, I do see the exception each time I run it (with 4 CPUs). ADDENDUM - just tried with --num-threads=1 and I still get the exception - any ideas?
