Is there a backtrace? This could indicate files actually disappearing somewhere (thus SRE-swift-storage).

Logstash didn't provide a backtrace in this instance. Here's what I'm looking at, for reference: https://logstash.wikimedia.org/#dashboard/temp/AVMa6iSgO3D718AO1yx2

I wonder if this is related to 'store' ops with TempFSFile objects for async swift writes...

aaron mentioned this in T128096: Unable to delete, restore/undelete, move or upload new versions of files on several wikis ("inconsistent state within the internal storage backends").Feb 26 2016, 11:46 PM
