<div>Hi,</div><div><br></div><div>Thank you all for you suggestions.</div><div>After updated the table fixed_ips and floating_ips, this problem was eventually fixed.</div><div><br></div><div>I finally figure out how to reproduce this problem:</div>

<div>Hi,</div><div><br></div><div>I have an Essex cluster with 6 compute nodes and one control node, and it worked fine in the past several months. Last week, since someone deleted an instance in a project, no new instance can be launched in that project. </div>
<div><br></div><div>When create a new instance in the project, it displays:</div><div><b style="font-size:13px;color:rgb(185,74,72);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;line-height:18px;background-color:rgb(242,222,222)">Error: </b><span style="font-size:13px;color:rgb(185,74,72);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;line-height:18px;background-color:rgb(242,222,222)">An error occurred.
