[mkgmap-dev] Mkgmap appears to hang on some split files

Mon Sep 28 08:36:08 BST 2009

While trying to get a new world map update out the door I noticed that 
Mkgmap sometimes hangs on an OSM data file produced with Splitter. When 
this happens the CPU is at 100% constantly for hours (e.g. all night) 
until I kill the process. The problem occurs in r1222 and also r1228.

The following command was used for Mkgmap (I know the code-page is 
redundant):

java -Xmx1792M -ea -jar mkgmap.jar --latin1 --code-page=1252 
--name-tag-list=name:en,int_name,name --remove-short-arcs 
--add-pois-to-areas --make-opposite-cycleways --link-pois-to-ways 
--description='OSM World Routable' --route --series-name='OSM World 
Routable'

Some problematic OSM files are below (created with Splitter r97 and 
max-nodes=1.200.000):
