</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">thanks for the report.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">We are aware that we do have a bug somewhere in the FreeSpaceMgr (as shown in the partially quoted stacktrace).<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">However, as explained in [1], this is just a symptom. As long as we cannot find the actual cause (or multiple causes of course :) ), its hard for us to fix something like this.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">This might be a race condition, but also something reproducible, once you know how :)
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">For now, it would help us if you can tell us what you were doing BEFORE that exception happened (before the auto-place command was executed)<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">As a workaround for now, you can simply restart the controller, that cleans the internal "pending" list of the FreeSpaceMgr (see [1] for more details)<o:p></o:p></p>
