To which values are you setting MAVEN_OPTS? It should be no problem so set it to 1024M. — oers, May 04 '11 at 06:18

There are a few properties to look at. In addition to cobertura.maxmen (per Raghuram's pointer above, look at the configuration for the surefire plugin. Make sure that forkMode is not never - but experiment.

Note in the description of the jvm property that "JVM settings are not inherited from MAVEN_OPTS." Try setting your memory options there, instead.
