<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">In my case, for every run, I do unstack.sh, clean.sh, sudo rm -rf devstack, sudo rm -rf /opt/stack. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Then I go get everything fresh and stack.sh, and a full run of smoke tests<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Few iterations of this sequence will get you into this condition. Once in this condition - clean.sh and unstack.sh, nothing helps, it fails solid 100% of times. If reboot the VM, everything works just fine for next 10-20 cycles until it
hits the same condition. So, I am planning on modifying the script to reboot the VM every two hours or so....as a work around....but, the underlying problem occurred close to Ichouse check-ins. I started to notice this few days earlier than the Icehouse deadline,
prior to that I was running the same sequence without any issue (for several weeks) - if that helps any...<o:p></o:p></p>

<p class="MsoNormal">So, honestly, running stack.sh / unstack.sh that many times in a row<br>
really isn't expected to work in my experience. You should at minimum be<br>
doing ./clean.sh to try to reset the state further.<br>
