title: Heroku Hobby server still sleeps or issue with NodeJS?
body: <p>I've noticed that my NodeJS application which resides on a Heroku Hobby server after no activity does a "soft restart". By that I mean it doesn't do big actions like reinitialize the ORM system or recreates the HTTP server, however it does seem to forget callback functions and <code>global</code> variables or any variables that were dynamically created and held in memory.</p>
  
  <p>Does Heroku still "sleep" even with the Hobby plan or is it something related to NodeJS?</p>
