How Do You Deal With An Exception Raised By Celery (not Your Code)?

So in my flask app right now I am using Celery to deploy servers on remote machines. Right now, I have an enum, status, which indicates the lifecycle of my deployment process: @cel

Solution 1:

In redis 2.4 there is a hard coded limit of max number of connections which is 10,000. In redis 2.6+ you can specify the max number of clients in redis.conf. also this is not a problem of celery your broker redis refused to accept connections that's the problem.

Set the max number of clients that can be handled by redis simultaneously using redis CLI. Check out redis clients
