<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>
<p>This is my top after rebooting yesterday at 17:00 :</p>

<p>When controller is getting out of memory everything goes extremely slow. Restarting apache2 and heat solves the problem. ;-)</p>
<p>Be lucky next week. :-)</p>

Try using htop,<br /> truss/strace and other debugging tools. You might also be a victim of<br /> resource bottlenecks, like your HDD are serving slow or it may be that your<br /> neutron conf is inappropriate at some point. If this ain't a production<br /> environment, try troubleshooting rather than going for old installation.<br /><br /><br /> On Aug 18, 2016 21:56, "Satish Patel" <<a href="mailto:satish.txt@gmail.com">satish.txt@gmail.com</a>> wrote:<br /><br /> I have recently install mitaka openstack using RDO on HP DL360 G9<br /> server with 16GB memory. but after installation it took all of my<br /> memory and suck all my swap memory too. and it was extremely slow.
