I'm only guessing here and might be grossly wrong about my hunch. Are you reusing your JVMs across tasks? Could you see if this goes away without reuse?
Would be good if you can monitor your launched Tasks (JConsole/VisualVM/etc.) to affirm that there's either a code-based memory leak or some other funny issue relating to loading native libraries into the JVM.

Or do some succeed (perhaps the first wave)? -- Harsh J www.harshj.com
