Net::ResourceBusyError Permission denied

Hi,
I have question about using Semian.
I configured simple NetHttp adapter (like in README):
config/initializers/semian.rb

SEMIAN_PARAMETERS = { 
  tickets:           ENV['SEMIAN_TICKETS'].to_i,
  success_threshold: ENV['SEMIAN_SUCCESS_THRESHOLD'].to_i,
  error_threshold:   ENV['SEMIAN_ERROR_THRESHOLD'].to_i,
  error_timeout:     ENV['SEMIAN_ERROR_TIMEOUT'].to_i
}.freeze

Semian::NetHTTP.exceptions += [::OpenSSL::SSL::SSLError]
Semian::NetHTTP.semian_configuration = proc do |host, _port|
  case(host)
  when 'site1.com')
    SEMIAN_PARAMETERS.merge(name: 'site_1')
  when 'site2.com')
    SEMIAN_PARAMETERS.merge(name: 'site_2')
  else
    nil
  end
end

I tested it on development, and all was looks good. But problem was shows on after production deployment. When I try execute http request from rails console then I getting error:

2.3.6 :090 > RestClient.get('https://site1.com')
Net::ResourceBusyError: [nethttp_site_1] semget() failed, errno: 13 (Permission denied)

In this time Semian.resources return blank hash.

Could you explain me what is wrong? I don't understand this error.

Is this on OS X? Bulkheads (i.e. tickets) are not supported on OS X. We just disable them in development and test.

[fstybel]

I working on OS X. But server works on Docker container in Amazon with system: ubuntu 16.04

[sirupsen]

Yep, tickets on OS X is not supported. See README.

Feel free to revive #51
