Sometimes the default memory limit on Java VMs is very small.  To fix,
edit the file DW4UI.sh and allocate yourself enough ram to hold the
image + 8MB for DW itself.

You will see a line like:

java -XX:+UseConcMarkSweepGC -jar DW4UI.jar --backup &

Change this to:

java -XX:+UseConcMarkSweepGC -Xmx256m  -jar DW4UI.jar --backup &

for instance to allocate 256mb.  This doesn't mean it will necessarily
use 256mb, just that it can if it needs to.  You can view memory use
with the same dw s st command or via the graph on the server tab.
