I am using the Redis Cloud add-in on my Heroku application and I keep getting this error sporadically. I have tried flushing the redis DB and restarting dynos and that seems to fix it but I am curious why this is happening so often.
I am running worker dynos that use this redis DB and I am using python-rq to schedule jobs on the worker queues.
