my rails server seems like it is logging everything twice, not sure what is going on here, what should I do to investigate this ?
Have a look at this issue
Try adding the following code to you config/application.rb
if Rails.env.development?
# Don't log to STDOUT, by default rails s will handle it
config.logger = Logger.new('/dev/null')
else
# Don't log to file, sending everything to unicorn file.
config.logger = Logger.new(STDOUT)
end
