Comment 4 for bug 1166198

file proxy/controllers/base.py, line 694

        finally:
            # Ensure the queue getter gets a terminator.
>>> queue.resize(2)
            queue.put(success)
            # Close-out the connection as best as possible.
            if getattr(source, 'swift_conn', None):
                self.close_swift_conn(source)

if I commented queue.resize(2), then problem does not occur!
