Possible causes: PERF: switch redis driver to hiredis by SamSaffron · Pull Request #33773 · discourse/discourse · GitHub

Thanks for reporting, will revert for now, but can you tell us a bit more about how redis is configured in your environment? Is this a multi container setup?

truman · July 23, 2025, 8:12am

yeah,multi container setup. redis is a alone container.

sam · July 23, 2025, 8:13am

what version is it on? I suspect its an old version of redis that does not support hiredis.

truman · July 23, 2025, 8:15am

redis:7.4.3

sam · July 23, 2025, 8:24am

Any chance you can help out and report this to GitHub · Where software is built ?

Ideally a repro would be something that:

Runs the docker container for your redis. (and share with byroot for easy debugging)
Runs something like this against your config:

require 'hiredis-client'
require 'redis-client'
require 'redis'
Redis.new(... <- your IP etc..).info

.info should explode that is what we were running.

I recommend avoiding adding env cause you will end up forgetting about it

Instead simply rebuild, this has been reverted for now
