I see what you mean. I'll investigate why the socket was closed, I presume it could be a network problem, because the Redis server is separated from the one where the app resides, they communicate through the local network. Considering the servers have plenty of available resources, the app serves around 60 requests per second and the error only happens 3 or 4 times per day, I will look into the network.
Thank you for your time!
