title: Debug one node memory leak in memory graph
body: <p>I have noticed these memory leaks when I used Memory Graph:</p>
  
  <p><a href="https://i.stack.imgur.com/hk3gT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hk3gT.png" alt="NSMutableArray memory leaks"></a></p>
  
  <p>But I cannot manage to debug those memory leaks. The strange thing is that there is only one object in the graph when I open one of the leaks. The object is NSMutableArray. </p>
  
  <p>Should not there be at least two objects pointing at each other? How can I debug this leak?</p>
