Can't connect to redis after upgrading ruby - ruby

I'm trying to upgrade my app to Mongoid 3 and ruby 1.9.3. I was on 1.9.2 before. My app also uses Redis as a temp data store. No code changes have occurred and this was working fine before... now I'm getting the following error when I run the task that connects to Redis:
Can't assign requested address - connect(2)

My Redis is running and I checked the port #.

Are you using Redis 3.0.1? Try using Redis 2.2.2

Errno::EMFILE: Too many open files when upgrading to ruby 2.3

I just upgrade to ruby 2.3 in order to take benefits of the frozen_string_literal option but it produce me the error Errno::EMFILE: Too many open files in production.
When I downgrade to ruby 2.2.3, no more errors.

I did not find someone with this concern on the ruby bug tracker nor on stackoverflow and the ruby 2.3 is recent (<2 months).
How can I deal with this?

When using gem 'aws-sdk-core' with active record facing issue

I have installed the gem 'aws-sdk-core' and in my model I have define
class abcd < Aws::Record::Base
ab = Pathname.new("#{Rails.root}/config/aws.yml")
cd = YAML::load(ERB.new(File.read(path)).result)
set_domain_name cd[Rails.env]['domain']
end
I am using this aws for running my rake tasks.so when am running my rake task its giving error :

Please help me in finding the solution. Thank's in advance!!!
The v2 AWS SDK for Ruby does not included the AWS::Record abstraction from v1. You can continue using the v1 implementation for now, as both v1 and v2 gems can be used in the same application.
Yeah i just ran into this issue and resolved. It is because AWS updated their gem to 2.0. If you update the gem to 2.0 different configuration is required.
If you want to using the version you had before, just change the Gemfile like below:
Gemfile
gem 'aws-sdk', '< 2.0'

Heroku precompile assets failed on Rail 4 app

I set
config.assets.initialize_on_precompile = false
in the application.rb. Assets were precompiled successfully locally by run
RAILS_ENV=production bundle exec rake assets:precompile
While the manifest-fingerprint.json(Rails 4.0 generates manifest.json instead of manifest.yml) was not detected when pushed to Heroku and Heroku tried to run precompile again. Then I got the error as:
Running: rake assets:precompile
rake aborted!

Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?

Seems the error was due to the file in the lib/student_module.rb, which was required in config/initializers/student_init.rb:
#lib/student_module.rb, the error pointed to this lineļ¼š
user_attributes = User.new.abttributes.keys
#config/initializers/student_init.rb
require 'student_module'
ActiveRecord::Base.extend Student
The error could be because Heroku initializes the app, which includes connection to the database. But I was not supposed to see the messages like
rake aborted!
could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
because I set config.assets.initialize_on_precompile false and also precompile the assets locally.
Any suggestions to solve this?Thanks!
You'll need to enable a labs feature on Heroku user-env-compile which gives the app access to the environment variables at compile time.
heroku labs:enable user-env-compile -a myapp
Read more about it at https://devcenter.heroku.com/articles/labs-user-env-compile

Debugging undefined method error in rake script

When running a local rake script that uses some ruby gems including configatron I get the following error. Can anyone suggest a good way to debug this as it seems that the ability to debug scripts like this is very not particularly intuitive.
rake aborted!

Many Thanks for any suggestions.
I have a feeling it could be related to this bug-report mentioned on the albacore github.
