Background Observation I notice a lot of "No connection available." logs from Redis Python client redis-py BlockingConnectionPool. Looking into the source of redis-py: try: connection = self.pool.get(block=True, timeout=self.timeout) except Empty: # Note that this is not caught by the redis client and will be # raised unless handled by application code. If you want never to raise ConnectionError("No connection available.") It happens when there is no connection in the pool available.
