We now always get one Rspec failure out of 1400 tests on the build server. Not always the same test that fails but so far its the same Controller post :create code that is run. When we run just two of these tests - we get the failure, but running one succeeds.

The failing code runs a deferred ApplicationJob using sucker_punch ( ie new thread ). The 'perform' code runs inside a 'with_connection' block:

# controllers/data_loads_controller.rb
...
def create
  ...
  DataLoadJob.perform_async(@data_load.id)
  ...

# jobs/data_load_job.rb
class DataLoadJob < ApplicationJob
  def perform( data_load_id )
    ActiveRecord::Base.connection_pool.with_connection do
      Admin::DataLoad.execute( data_load_id )
    end
  end
end

This does not happen locally (PostgreSQL 9.3), but does happen on the build server (PostgreSQL 9.2)

Rails:5-1-stable @90a3ce293def
PostgreSQL 9.2
Ruby 2.17
