Turns out that pull request fix was not the issue. It was the feature that was added to remove the most recent candle. i.e. drop_newest It caused the loop test of dlen at the bottom of the while true loop to fail so it never broke out of the loop. I downloaded a local copy and changed the following to fix this issue:

               if tstamp > self._last_ts:
                    if self.p.debug:
                        print('Adding: {}'.format(ohlcv))
                    self._data.append(ohlcv)
                    self._last_ts = tstamp
                    since = tstamp + 1

            data_length = len(self._data)
            if data_length >= limit:
                break

Works fine now.
