We have built an open-source, free Google Reader Alternative and have live users using the platform. It is hosted at http://reader.pykih.com and code is at http://github.com/pykih/reader
Until, last night my app was working fine and today morning it is down due to timeout.
We use DelayedJobs for all feed imports
This timeout is occurring on the homepage where there is no external service call, emails being set, etc. except may be push to GA
Heroku Support (as per them) is asleep right now and we will get an answer only on Monday. :-(
We went through a lot of past questions on Stack over flow about this issue but none seem to answer our issue.
Can someone please advice?

Heroku fixed itself 11 hours later. V annoying.

My Ruby on Rails app works fine in development on cloud9. When I push to Heroku, the application crashes immediately. 'heroku logs' shows:

I've tried using unicorn and puma, both with the .rb files Heroku provides, with no luck. I can't even get a console to run on Heroku. 'heroku run rails console' in the IDE shows 'Running rails console attached to terminal... up, run.9870' then brings me back to the IDE console, rather than Heroku's. The Heroku logs for the console command are:

Any suggestions on where to begin troubleshooting this?
Edit: I've set up an Ubuntu server on EC2, and I'm getting exactly the same thing when running in development and in production. I'm using pg for both. rails s -e development runs fine, rails s -e production crashes immediately, and nothing is logged (that I can find)
I've resolved the issue: I had to comment out "require 'rails/test_help'" in environment.rd then everything ran along nicely.
Although read many articles about this problem, I still couldn't solve those error,
Here is a part of the heroku logs, if it's less-information, I would update others code of the red mine source code.

I can't figure where is the reason that leads app crashed actually,
Thanks for answering...
Just out of curiosity, did you happen to generate your secret key?
Try running:
heroku run rake generate_secret_token
Not sure if it will help, but I know I've had an issue with this before.
I am facing this problem upon pushing my app to Heroku:
500 internal server error
ActionView::Template::Error...application.css isn't precompiled (see attached Heroku logs)
Also, ActionController::RoutingError (No route matches [GET] "/assets/rails.png"
I am using Twitter Bootstrap 2.0.1 and Rails 3.1.1 (see Gemfile below)
Any guidance would be much appreciated!

So based upon the heroku info that you provided I see that you are on the bamboo stack and that stack does not support Rails 3.1+. Only the cedar stack supports Rails 3.1+. You'll need to use the following command to create a new app on the cedar stack:
heroku create --stack cedar
This is the result of your stylesheets not being compiled. Heroku will attempt to run
rake assets:precompile
before deploying your app. If the precompile command fails it will fail silently for now. I actually have an open issue for this on Heroku
https://github.com/heroku/heroku-buildpack-ruby/issues/9
The most likely cause is that the Rakefile is trying to load (or access) a gem. Heroku buildpacks attempt to compile the stylesheets before they have access to the gemset so any requires will fail. The best way to avoid this is to wrap those requires in your Rakefile in environment specific conditionals:
if Rails.env == 'development' || Rails.env == 'test'
require 'somegem1'
require 'somegem2'
# whatever code is being used by those gems goes in this block
end
I'm using the Spawn gem in a rails 3 app - it's the rails3-adapted fork at https://github.com/rfc2822/spawn
My app is deployed on heroku, and when i tried to spawn i get this failure:
app[web.1]: ### ../controllers/messages_controller.rb:10:in `create_message': About to spawn
app[web.1]: spawn> parent PID = 1
app[web.1]: spawn> child PID = 49
app[web.1]: ### ../controllers/messages_controller.rb:17:in `create_message': After spawn
app[web.1]: Task Load (1.2ms) SELECT "tasks".* FROM "tasks" WHERE "tasks"."id" = 80 LIMIT 1
app[web.1]: PGError: server closed the connection unexpectedly
app[web.1]: This probably means the server terminated abnormally
app[web.1]: before or while processing the request.
I have this option in my config/database.yml, following the recommendation of the spawn documentation:
reconnect: true
Is it connected to this do you think?
Bit at a loss with this... before i go investigating, does anyone know what's causing this?
cheers, max
I ended up using the girl_friday gem instead, which is a simple forked-queue system. It worked great for me.
Having problems with some asset caching, using Dalli on Heroku with Rails 3.1. These are the errors in my logs:

Any thoughts about what's going on?
It looks like Dalli is not connection to a Memcache server? Have you enabled the Heroku Memcache addon (or otherwise configured a Memcache server)?
