<p>Thanks for the ideas! They are cheap clone servers using Intel® Server Board S5520HC with 48Gb of RAM. <o:p></o:p></p>
<p>-The nodes simply reboot, without any interesting logs. Not all at the same time.<o:p></o:p></p>
<p>-There's no automatic updates or anything like it.<o:p></o:p></p>
<p>-I don't think overheating is the problem, because they reboot early in the morning when they have no load at all. They usually reboot around 03:00 to 05:00 AM.<o:p></o:p></p>
<p>I had no idea about this bmc thing Ill check it out.<o:p></o:p></p>

<p class="MsoNormal">Hi,<br>
<br>
Your compute nodes reboot or are shut off?<br>
<br>
I am currently looking at some cases where VMs seem to spontaneously shut themselves<br>
off. At least from the nova logs’ perspective there is no difference to a normal shutdown,<br>
VM owners however confirm that they did not touch their VMs. So far I was unable to<br>
explain this.<br>
<br>
This is with Havana on a RHEL6 derivative, though.<br>
<br>
Cheers,<br>

> Hello guys, We have got a small Grizzly cloud running since the begging of 2013 with Ubuntu 12.04. 2 compute nodes, a storage node and a controller, nothing too fancy. Everything works just fine, but... the compute nodes reboot themselves periodically, sometimes
every 2 weeks, some times once a month. I've done almost everything I can think of: memory checks, analysed the logs, moved all the VMs to one node, and I just can't find the problem.<br>
