Thanks for the tip. I upped the additional swapfile size to 2GB and  
tried again, with the same results.

Granted I understand that expecting so much from this little machine  
is really pushing it, it will eventually just be running a small java- 
based server, that unfortunately requires jdk15. I wouldn't ever  
choose it on purpose.

With a total swap size of roughly 2.5GB still generating failures, is  
this a lost cause, or should I be looking for additional solutions?
