<p class="MsoNormal"><span style="color:#1F497D">Solution 1 sounds like how Openstack Heat handles an abnormal termination of the heat-engine (how it needs to properly clean up its stack locks)<o:p></o:p></span></p>

<p class="MsoNormal">Hi<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am check this launch pad issue. This issue is failed, when system application apply(retrieving docker image), sysinv-api exit unexpected. When service manager re-launch sysinv-api again, application status is in applying status.<o:p></o:p></p>
<p class="MsoNormal">So application could not be removed. There are two solutions.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Solution 1, when sysinv-api or sysinv-conductor launch, in __init__ function, check application status in database, if status is “uploading”, ”applying” or “removing”, change the status to “upload-failed”, “apply-failed” or “removed-failed”<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Solution 2, add perform-abort action for upload or apply. Use a flag to quickly exit and upload and apply action, and set database to “upload-failed” or “apply-failed”.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
