[mkgmap-dev] Fail to build map with r1908 and sea-generator=extend-sea-sectors

Thu Apr 7 17:45:56 BST 2011

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.
