Why is this Eventmachine process being terminated?
Hi guys, So I've been having some issues running an eventmachine worker on Heroku. After some tedious debugging I realized that it didn't appear to be what the event machine was doing that caused the problem. A simple eventmachine loops that does nothing but logging a tick every second is killed as well. My problem: The eventmachine process is being terminated within 15 seconds from start. A SystemExit exception is thrown. My setup: The rake task jobs:work uses the daemons gem to start a new daemon that runs the eventmachine reactor. Here is the three simple files used: https://gist.github.com/061ab6973843c31dace3 And the logged output: https://gist.github.com/b7beaeed48b8059efc4b What makes it this difficult to have an EM-process running? It's running perfectly on a local machine, of course. Cheers -- You received this message because you are subscribed to the Google Groups Heroku group.

Hi, Are you're sure that you've added _all_ necessary files to your commit and pushed it to remote?

Re: First RoR application. File not found
I'm curious what you are removing the period from. Is this environment.rb, or part of a require statement? I ask because I can't recall specifying a path to *anything* in rails. Can you show us the offending line? You'd probably get better help. jeff On Mon, Dec 6, 2010 at 4:58 PM, fikre fikrelegue...@gmail.com wrote: Hi Im trying to run my first Rails app on heroku.

Re: Error when using memcached uninitialized constant Memcached (NameError)
Remove the gem 'memcached' line from your gemfile and you should be good to go. You only need the dalli gem. -- You received this message because you are subscribed to the Google Groups Heroku group.

Re: Why is this Eventmachine process being terminated?
Thanks David, it makes perfectly sense. For people playing around with the daemons gem, this is the equivalent of setting the :ontop option to true.

With the way our workers work, you should have rake jobs:work launch a foreground process, and we will keep it alive.

I suggest not using the Daemons gem at all. Here's a hello-world
eventmachine daemon running via the DJ convention in your Rakefile:
task 'jobs:work' do
require 'eventmachine'
EM.run do
EM.add_periodic_timer(1) do
puts Tick! #{Time.now}
end
end
end
Dustin Sallings, one of the authors of memcached, put it beautifully
when he said: Self-daemonizing programs start you down the path to
hell.. See:

No joy with Rails 3: no such file to load -- dispatcher (LoadError)
I've been trying to move an app from Rails 2.3.8 to 3.0.3. The 2.3.8 version runs fine on Heroku. Modified for Rails 3.0.3, it runs on my Windows/MySQL development machine. But I haven't been able to get it to run at all on Heroku. bundle install runs clean, and git push runs clean. All I get from Heroku is App crashed. In the console log (below), Rails can't find dispatcher. But I don't see dispatcher or dispatcher.rb is in the file tree. What's missing? If I'm missing a Gemfile entry, how can I find out what it is? Thanks very very much for any help at all! $ heroku logs --app myapp == dyno-3674715.log (crash) == /disk1/home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/ activesupport-3.0.3/lib/active_support/dependencies.rb:239:in `require': no such file to load -- dispatcher (LoadError) from /disk1/home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/ activesupport-3.0.3/lib/active_support/dependencies.rb:239:in `require' from /disk1/home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/ activesupport-3.0.3/lib/active_support/dependencies.rb:227:in `load_dependency' from /disk1/home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/ activesupport-3.0.3/lib/active_support/dependencies.rb:239:in `require' from /usr/ruby1.8.7/lib/ruby/gems/1.8/gems/thin-1.2.6/lib/rack/ adapter/rails.rb:43:in `load_application' from /usr/ruby1.8.7/lib/ruby/gems/1.8/gems/thin-1.2.6/lib/rack/ adapter/rails.rb:23:in `initialize' from /home/heroku_rack/heroku.ru:29:in `new' from /home/heroku_rack/heroku.ru:29 from /home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/ lib/rack/builder.rb:46:in `instance_eval' from /home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/ lib/rack/builder.rb:46:in `initialize' from /home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/ lib/rack/builder.rb:63:in `new' from /home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/ lib/rack/builder.rb:63:in `map' from /home/heroku_rack/heroku.ru:18 from /home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/ lib/rack/builder.rb:46:in `instance_eval' from /home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/ lib/rack/builder.rb:46:in `initialize' from /home/heroku_rack/heroku.ru:11:in `new' from /home/heroku_rack/heroku.ru:11 from /home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/ lib/rack/builder.rb:46:in `instance_eval' from /home/slugs/.../mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/ lib/rack/builder.rb:46:in `initialize' from /home/heroku_rack/heroku.ru:1:in `new' from /home/heroku_rack/heroku.ru:1 - Your application is requiring a file that it can't find.
