ruby-on-rails - 连接超时。请就配置向我们提出建议

Question

我们正在使用 heroku redistogo lite 计划

有

````
# = Limits ===================================================================
maxmemory 52428800
maxmemory-policy volatile-lru
maxmemory-samples 3

maxclients 128
timeout 150

`````

在进程文件中

```
worker: bundle exec sidekiq -c 3 -v -q default -q medium

```

我的配置:

```
require 'sidekiq'
require 'sidekiq/web'
require 'log4r'

Sidekiq.configure_server do |config|
Sidekiq::Logging.logger = Log4r::Logger.new 'sidekiq'
Sidekiq::Logging.logger.level = Log4r::INFO
Sidekiq::Logging.logger.level = Logger::WARN
Rails.logger = Sidekiq::Logging.logger
  # config.redis = { db: 1 }
  config.redis = { url: ENV['REDISTOGO_URL'] }
  config.server_middleware do |chain|
    chain.add Sidekiq::Status::ServerMiddleware, expiration: 90.minutes # default
  end
end

Sidekiq.configure_client do |config|
  config.redis = { size: 1, url: ENV['REDISTOGO_URL'] }
  config.client_middleware do |chain|
    chain.add Sidekiq::Status::ClientMiddleware, expiration: 90.minutes # default
  end
end

# ActiveRecord::Base.logger = Sidekiq::Logging.logger
Sidekiq::Web.set :session_secret, Rails.application.secrets[:secret_token]
Sidekiq::Web.set :sessions, Rails.application.config.session_options

`````

错误:
