Nakor, the error tells you that the java process has insufficient memory available. You can change the maximum available memory for the java process with the java parameter -Xmx1000m (for 1000 megabyte). Example: java -Xmx1000m -jar mkgmap.jar data.osm The reason why you didn't see this error with 1903 might be some little more memory requirement. (this is just a guess...) Please try if you can reproduce the error and/or increase the memory parameter. WanMil

Hello,

I have a map that built correctly with 1903 which also builds correctly with 1908 if I use sea-generator=multi-polygon but fails to build in r1908 with sea-generator=extend-sea-sectors. The error is:

java.lang.OutOfMemoryError: GC overhead limit exceeded at uk.me.parabola.imgfmt.app.net.NOD1Part$BBox.contains(NOD1Part.java:121) at uk.me.parabola.imgfmt.app.net.NOD1Part.addNode(NOD1Part.java:227) at uk.me.parabola.imgfmt.app.net.NOD1Part.subdivideHelper(NOD1Part.java:277) at uk.me.parabola.imgfmt.app.net.NOD1Part.subdivide(NOD1Part.java:239) at uk.me.parabola.mkgmap.general.RoadNetwork.splitCenters(RoadNetwork.java:249) at uk.me.parabola.mkgmap.general.RoadNetwork.getCenters(RoadNetwork.java:254) at uk.me.parabola.mkgmap.build.MapBuilder.makeMap(MapBuilder.java:220) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:101) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:65) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:224) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:221) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)
