I think it's worth trying to run unicorn on heroku instead of webrick. 我认为值得尝试在heroku而不是webrick上运行unicorn 。 Heroku became terrible at running other webservers for some reason. Heroku由于某种原因而无法运行其他Web服务器。 I was running thin perfectly fine last year, but this year, when I had some code to update and tried to upload to heroku, Thin was breaking heroku. 去年，我的运行状况非常好，但是今年，当我有一些代码需要更新并尝试上传到heroku时，Thin打破了heroku。

  1. add gem 'unicorn' 添加gem 'unicorn'
  2. bundle install
  3. create config/unicorn.rb 创建config/unicorn.rb
  4. Add the following in config/unicorn.rb 在config/unicorn.rb添加以下config/unicorn.rb 
config/unicorn.rb
worker_processes Integer(ENV["WEB_CONCURRENCY"] || 3)
timeout 15
preload_app true

before_fork do |server, worker|
  Signal.trap 'TERM' do
    puts 'Unicorn master intercepting TERM and sending myself QUIT instead'
    Process.kill 'QUIT', Process.pid
  end

  defined?(ActiveRecord::Base) and
    ActiveRecord::Base.connection.disconnect!
end 

after_fork do |server, worker|
  Signal.trap 'TERM' do
    puts 'Unicorn worker intercepting TERM and doing nothing. Wait for master to send QUIT'
  end

  defined?(ActiveRecord::Base) and
    ActiveRecord::Base.establish_connection
end

Finally commit changes and push to heroku 最后提交更改并推送到heroku
