Rails 7 - Unicorn 6.1.0 -- reaped with preload_app

[Cédric Carrard]

Hello

Since the update to rails 7 and ruby 3.1.1 I have errors with unicorn
6.1.0 (we use docker-compose, nginx, sidekiq, postgresql and
unicorn-worker-killer).

1:10280 configurator.rb:49] Unicorn -- reaped #<Process::Status: pid
415 exit 1> worker=15

Here is the unicorn configuration:

require 'semantic_logger'

worker_processes(File.read('/proc/cpuinfo').scan(/^processor\s*:/).size
* (ENV['WORKERS_PER_CPU'] || 2).to_i)
timeout 300
preload_app true
listen(ENV["PORT"] || 3000)
logger SemanticLogger['Unicorn']

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

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

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

  SemanticLogger.reopen

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

If I remove the preload_app it works (but apparently it is recommended
to leave this setting)

Do you have any idea where the problem could be?

Thanks for your help
