Django Redis connection error in heroku: Error 110 while writing to socket. Connection timed out

Question

I'm using Redis for caching in my Django project which is hosted on Heroku.

During Redis connection, on random times I got the below error message

Error 110 while writing to socket. Connection timed out.

I'm using the below packages with versions

• python-3.6.8
• Django-2.2.2
• redis-3.2.1
• celery-4.3.0

Also, I'm access Redis using worker ( celery sometimes).

Can someone please suggest me to get rid of this problem or any other countermeasure to handle this problem.

Thanks in advance...

Answer 1

There are several possible causes for this--the most usual occurs where you have lots of cache evictions caused by the maxmemory setting on redis being too low. Check to see your redis size using the redis-cli stats command and see if you need more memory to redis.
