The problem is that the swift server returned a 408 HTTP code, and S3QL doesn't know what to do with it. Probably retrying would be the right choice, but to be sure I'd really need to have some documentation of the status codes and their meaning that Swift may return. For example, S3 has a comprehensive listing of status codes and the expected response of the client at http://docs.aws.amazon.com/AmazonS3/latest/API/ErrorResponses.html. But there is nothing comparable in the Swift documentation at http://docs.openstack.org/api/openstack-object-storage/1.0/content/PUT_createOrReplaceObject__v1__account___container___object__storage_object_services.html. This is why, in general terms, S3QL's Google Storage and Amazon S3 support is more robust than OpenStack/swift support. If you report this issue at https://bitbucket.org/nikratio/s3ql/issues I can add support for 408 error to S3QL. However, in order to fix this properly it'd be great if you could contact your storage provider and ask them if they have information about the error codes that the swift server may return, and how the client is supposed to react to them.
