Resque Pool and NewRelic

resque_pool.rake

require 'resque/pool/tasks'

# this task will get called before resque:pool:setup
# preload the rails environment in the pool master
task "resque:setup" => :environment do
  # generic worker setup, e.g. Hoptoad for failed jobs
end

task "resque:pool:setup" do
  # close any sockets or files in pool master
  ActiveRecord::Base.connection.disconnect!
  # and re-open them in the resque worker parent
  Resque::Pool.after_prefork do |job|
    NewRelic::Agent.after_fork(:force_reconnect => true)
    ActiveRecord::Base.establish_connection
  end
end

After running this in production for a while, I have to say: Don't do this. For some reason, jobs just silently fail and die.
