title: Finding which child is using up all my memory in Erlang
body: <p>I am troubleshooting a crashing Erlang program.  It runs out of memory.  It has several children started by OTP (<code>one_for_one</code> in the supervisor), and some started with <code>spawn</code>.</p>
  
  <p>I am starting the program and falling into the Erlang prompt <code>(test@test)1&gt;</code>.  I'd like to see how much memory each of these children is using from here.  I've searched online and not found anything, but this seems like a common enough need to already have a solution.</p>
  
  <p>How can I find the memory utilization of each child, in Erlang, from the system prompt?</p>
