Thought I'd try freenet from this url...

http://www.freenetproject.org/index.php?page=download

...when I check on Java, which it needs, I find this...

baal: {1} pkg_info | grep jre
sun-jre14-2.8       Sun's Java(tm) 2 Runtime Environment 1.4.2
baal: {2}

...so it seems okay to start freenet, but when I do I get this..

baal: {1} cd freenet
baal: {2} sh start-freenet.sh
Detected freenet-ext.jar
Detected freenet.jar
Starting Freenet now: Command line: java -Xmx128m freenet.node.Main
Done
baal: {3} Java HotSpot(TM) Client VM warning: Can't detect initial 
thread stack location
Error occurred during initialization of VM
Could not reserve enough space for object heap

baal: {3}

...so my question is, "Do I need more swap or something? Or is it
something else?"
