             Summary: Memory leak when LinkedList element is destroyed
                 Key: MNEMONIC-215
                 URL: https://issues.apache.org/jira/browse/MNEMONIC-215
             Project: Mnemonic
          Issue Type: Bug
            Reporter: Johnu George
            Assignee: Wang, Gang
            Priority: Critical
             Fix For: 0.6.0-incubating


Here is the implementation of the destroy function in LinkedList node

  @Override
  public void destroy() throws RetrieveDurableEntityError {
    m_holder.destroy();
    if (null != m_item) {
      m_item.destroy();
      m_item = null;
    }
    if (null != m_next) {
      m_next.destroy();
      m_next = null;
    }
  }

Next is destroyed only when m_next is not null. m_next can also be null if next item is not loaded into memory from PMem. It is required to first restore the item using getNext and then call destroy.
