Guys I'm trying to restart my unicorn service and seems it get stuck on this

[2019-03-06T20:45:05.938802 #7614] INFO -- : Refreshing Gem list

/usr/local/rvm/gems/ruby-2.5.1@citius_artis/gems/unicorn-5.5.0/lib/unicorn.rb:49:in

`block in builder': wrong number of arguments (given 0, expected 2)
(ArgumentError)

Did not change anything on gemfile

If I run rails s -e staging the rails starts normally

Any ideas?

My unicorn.rb config

APP_ROOT = File.expand_path(File.dirname(File.dirname(__FILE__)))

# puts "APP ROOT ->>> #APP_ROOT"

if ENV['MY_RUBY_HOME'] && ENV['MY_RUBY_HOME'].include?('rvm')
 begin
 rvm_path = File.dirname(File.dirname(ENV['MY_RUBY_HOME']))
 # puts "RUBY HOME ->>> #rvm_path"
 rvm_lib_path = File.join(rvm_path, 'lib')
 # $LOAD_PATH.unshift rvm_lib_path
 # require 'rvm'
 # RVM.use_from_path! APP_ROOT
 rescue LoadError
 raise "RVM ruby lib is currently unavailable."
 end
end

ENV['BUNDLE_GEMFILE'] = File.expand_path('../Gemfile', File.dirname(__FILE__))
require 'bundler/setup'

if ENV['RAILS_ENV'] == 'production'
 worker_processes 2
else
 worker_processes 2
end

working_directory APP_ROOT

preload_app true

timeout 60

listen APP_ROOT + "/tmp/sockets/unicorn.sock", :backlog => 64

pid APP_ROOT + "/tmp/pids/unicorn.pid"

stderr_path APP_ROOT + "/log/unicorn.stderr.log"
stdout_path APP_ROOT + "/log/unicorn.stdout.log"

before_fork do |server, worker|
 # puts "SERVER ->>> #server"

 defined?(ActiveRecord::Base) && ActiveRecord::Base.connection.disconnect!

 old_pid = APP_ROOT + '/tmp/pids/unicorn.pid.oldbin'
 if File.exists?(old_pid) && server.pid != old_pid
 begin
 Process.kill("QUIT", File.read(old_pid).to_i)
 rescue Errno::ENOENT, Errno::ESRCH
 # puts "Old master alerady dead"
 end
 end
end

after_fork do |server, worker|
 if defined?(ActiveRecord::Base)
 config = ActiveRecord::Base.configurations[Rails.env] || Rails.application.config.database_configuration[Rails.env]
 config['pool'] = ENV["DB_POOL"] || ENV['RAILS_MAX_THREADS'] || 5

 ActiveRecord::Base.establish_connection(config)
 end
end

I was having the same problem and following John Smith's advice this worked for me:

bundle exec gem list | grep unicorn # returns unicorn (5.5.0)

change Gemfile to gem 'unicorn', '5.4.1'

bundle install

bundle exec gem list | grep unicorn # returns unicorn (5.4.1)

Then I was able to restart unicorn without error

Looks like there was a bug introduced in 5.5.0
https://bogomips.org/unicorn-public/20190307022859.mxz7m3mbspujo4c2@dcvr/

I tested his patched version and it works:

Set unicorn version in Gemfile

gem "unicorn", "~> 5.5.0.1.g6836"

And ran bundle update unicorn
