It is like session issue ? or there is some issue as we are uploading all files one by one and still there is error as unable to obtain exclusive access to this record. \n","author":{"url":"https://github.com/sahilbatraa","@type":"Person","name":"sahilbatraa"},"datePublished":"2015-06-26T07:35:42.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/68/Force.com-JavaScript-REST-Toolkit/issues/68"}
