Removing orphaned processes on Sidekiq

Sometimes your Sidekiq processes exit prematurely and the process name is still showing on Sidekiq UI, you have to remove it manually in Redis.

1. Access Redis from cli

redis-cli your-redis-server-url

2. Sidekiq uses processes set to store processes ids, so list them with SMEMBERS

> SMEMBERS processes

1) "redis-1:6379:aaaaaaaaaa"
2) "redis-2:6379:bbbbbbbbbb"

3. Remove unwanted process name with SREM

> SREM processes redis-2:6379:bbbbbbbbbb
