Could you run "jps -v" to see what the full set of JVM parameters are for the JVM that is running the task that is failing? I can't imagine a situation where anywhere near 48GB would be needed, so I'm assuming that this is a question of your memory settings not being correctly propagated to the task JVMs somehow. - Gabriel
