问题
I have a django application leveraging celery for asynchronous tasks. I've been running into an issue where I reach the max number of redis connections. I am fairly new to both celery and redis.
I'm confused because in my config I define - CELERY_REDIS_MAX_CONNECTIONS = 20 which is the limit on my redis plan.
For experimentation, I bumped the plan up and that solved the issue. I am confused, however, that I am running into this problem again after defining the max number of connections. I downgraded the plan and set the limit to the plans max.
I am wondering if the BROKER_POOL_LIMIT needs to be changed.
Is there anything I am missing to help solve connection errors and celery.
Is it possible to figure out how many connections all of my tasks need? I have 16 jobs running every minute.
Another thought, I noticed that connecting the redis cli threw the connection error, is it possible that I am at the limit, and accessing the cli is putting me over?
I also cant kill connections because I cannot connect to the redis cli while it throws this error.
