title: How to figure out memory leak in node process
body: <p>My nodejs application is leaking memory, so I was trying to use heapdump to compare the memory changes, unfortunately, memory does not change in headdump, but my nodejs process is leaking memory.So I was thinking native-modules could be one culprit, then I was using mtrace to figure it out. 
  But I could not understand Module "/lib64/libstdc++.so.6" is increasing the size. </p>
  
  <p>Does anyone could help give me some suggestions of tools or ways to figure out memory leak that does not happens in heap itself.</p>
  
  <p>Many appreciate.</p>
