      Steps to Reproduce (be specific):
          The problem with Linux occurs when Swap is intensively active.
          Increasing the "-Xms128m -Xmx128m" parameters seems to solve/hide the problem.
          I am unable to write a small application to show the problem because a big activity is needed.
