  ****************************************************************
  * RECOMMENDATION: If the Java Virtual Machine crashes with     *
  *                 Out Of Memory exceptions, this could be      *
  *                 due to a build up of Service Runtime         *
  *                 Exceptions, causing a memory leak to build   *
