The heap must be a memory area whitout holes. On windows machine with 2G of ram you can't get more than 1,3/1,5 GB of ram for the heap. If you need more heap: -try the vodoo to fine tune your GC settings: fine tune the JVM is more like magic than science -take 2 more GB of RAM -take a lot more GB, install a linux 64bit :) I run my analysis pipelines on xeon quad, with 8G of RAM. The heap is usually set to 2G, 2,5Gb, it depends. But my documents are very small!
