<p>Same memory problems with Ubuntu 16.04 and Mitaka packages included by default.</p>
<p>Looks like each new version uses more and more memory. I began using 4GB in Juno but now I use 8GB in Mitaka. I need HA so I need three servers -> 24GB .</p>
<p>It looks like each component spends low memory but, there are a lot of components!</p>
<p>The memory usage increases with time. Heat module and horizon are my biggests problems.</p>
