<p class="MsoNormal">After uploading file-segments, the final request to create a static large object manifest will validate all of the referenced segments with HEAD requests. All the referenced SLO segments have to return a successful 2XX response before
the manifest object will be created.<o:p></o:p></p>

<p class="MsoNormal">I can see you included the partial logs from transaction tx30e82374b98845bab6883-0062e7d225 and txf09676de38964ca299b77-0062e7dcc8 - but it's not entirely clear what happened between the object-server PUT that created the file-segment object
(response 201) and the HEAD that failed (response 404).<o:p></o:p></p>

</div>
<div>
<p class="MsoNormal">It appears both requests went to the same node (swift0-1-object01) and device (/mpathc) - so unless the file was deleted (or expired, or corrupted, or rebalanced) I would not expect the 404 response. Can you check on the file-segment object
AFTER the SLO validation fails? Does it keep returning 404? Where did it go?!<o:p></o:p></p>
