body: <p>I'm developping an app with React native and my last version in release mode crashes after 20-30 seconds with the following generated logcat:</p>

  <p>The app never crashes in dev mode.</p>
  
  <p>How can I know what causes this? Is there a leak somewhere? What steps are to be followed to know more about it?</p>
