<div>That was exactly the problem and the fix.</div>

<div>I was able to issue the enclosed date command and restart one/sunstone (no server reboot required).</div>

<div><font size="2" face="Arial">I think this could be related to the "leap second bug". Did you notice any lag prior to this past weekend?</font></div>

<div><font size="2" face="Arial">If not, try issuing this command on your cloud controller(s): date -s "`date`"</font></div>

<div><font size="2" face="Arial">Alternatively, you can reboot. I had pretty much an identical issue as you and it appears it was related to the "leap second bug". A reboot fixed it for me, but some people have had success with the date command.</font></div>

</div>
<div>My company is running OpenNebula 3.4. It's been running in production now for just over a month. Recently we started noticing issues in Sunstone. Mainly the VM List wouldn't load and several other parts of the GUI would not load. I attempted to restart
Sunstone and oned and the problem persists.</div>
<div><br>
</div>
<div>One item of note is the high CPU utilization of several of OpenNebula's processes. Here are the top details from our cloud controller (this server also serves up the shared data for our VMs via NFS):</div>

<div>The running VMs are not impacted in any way – we have resorted to leaving one stopped until we can resolve the issue. What can/should I look at to begin debugging this problem? </div>
