Mysterious crash deploying on Dreamhost

Hey; I've written up my first simple (toy) Helma app, and I'd like to
get it deployed. I've got a hosting account with Dreamhost, and they
seem to have Java installed. I'm using the latest 1.6.0-rc1.

Everything seems to work fine when I run start.sh. I can load the app
in my browser on port 8080. However, after a few seconds (about 10 or
so) I get the following message in the console:

./start.sh: line 78:  9419 Killed                  $JAVACMD $JAVA_OPTIONS -jar "$INSTALL_DIR/launcher.jar" $SWITCHES

None of the log files show any indication of something going wrong,
but the server mysteriously dies. This app works fine on my own
system.

Any idea what would cause this? My suspicion is that it's getting
killed for using too much CPU or memory as those resources are often
tight on a shared-host environment like this. Has anyone gotten
Helma to work on Dreamhost?

thanks,
