The owner is the one who obtained the item via Get Next Item.

There should be a Flag value of either ""True"" or ""False"". In case of a system exception you could use ""True"" and decide the retry attempts in the work queue settings (based on the consensus with the client).

I've never seen the 'The specified item was not locked by this...' error produced zany other way.
