#13 java.lang.OutOfMemoryError: Java heap space

[Richard de Vroede]

Exception in thread "main" java.lang.OutOfMemoryError:
Java heap space

CPU (AMD3700+) goes to 100% while running, but memory
(1 Gb + pagefile) is still plenty (300Mb free).

I used it on a module having around 2 Gb of hakpack
resources and around 150 areas.

Command used: MiniMapExport.cmd
D:\games\nwn\modules\mymodule.mod -nwn D:\games\nwn
-useAreaName -d D:\mymodule\AreaMaps

Java by default limits itself to a pretty small heap. I
should probably change the setup file to generate a script
with an increased heap size.

In the meantime, you can adjust the MiniMapExport.cmd script
yourself. Basically, right after the "@java" put a -Xmx256m
so the command would like something like:
@java -Xmx256m -cp...

This should increase Java's maximum heap size to 256 meg. I
think it defaults to 32 or 64. You can increase it larger
as needed but I'd be sort of surprised if you needed to go
too large. The minimap exporter doesn't cache all 2 gb,
just what it needs.

I should probably add this to the documentation. Let me
know how that works out for you.

That not only did the trick, it also sped up the process
enormously..
It's done now in about 10 seconds!!
