Just a wild guess : Have you tried to use velocity 1.3.1 for the generator
? Henning has reported memory leaks of velocity 1.4 that were not there in
velocity 1.3.1, so velocity's internal structure seems to have changed.
NB: The generator does not need to run on the same machine as the runtime.
So you can also change the os limits on a development machine used to
generate the om model, and still keep the original os limits on the
production machine.
