title: ActiveMQ default port 61616 collides with IANA ephemeral port range
body: <p>ActiveMQ's default port <code>61616</code> collides with the IANA recommended range for <a href="https://en.wikipedia.org/wiki/Ephemeral_port" rel="nofollow">ephemeral ports</a> (<code>49152-65535</code>).<br>
  This can keep ActiveMQ from binding to <code>61616</code> if it is used by an existing TCP connection.</p>
  
  <p>Collisions shouldn't be a problem if the ActiveMQ broker is started on system boot, since the OS would likely start at the low end of the port range and wouldn't collide with <code>61616</code> until tens of thousands of TCP connections had been established.<br>
  However, collisions are possible if the ActiveMQ broker is restarted any time after boot.</p>
  
  <p>Should ActiveMQ users not be using <code>61616</code> for real installs, or should port <code>61616</code> be excluded from the server's ephemeral port range during deployment?</p>
