Rails 3.1 + Heroku = Workers Crash
So, I just hoisted up a brand new Rails 3.1.1 (Ruby 1.8.7) application.
Put a few suburbs in there, install Authlogic and create a new Heroku app. Pushed it to Heroku and ported DB.
And everything's good. I can create new user accounts with Authlogic and create new accounts in my models on Heroku.
It's a funny thing. If I increase my "work dynamics" from zero to anything, heroku logs show those workers are trying to get started and they crash.
But I don't have a set delay. And never introduced Delayed Job to this app
I also haven't provided any "advanced" gems other than Twilio or any advanced code. This is just a new rails app with authlogic. No new rake challenges.
One more note. On my local development machine, I tried to install Delayed Job in another application a while ago and failed. Could the ghosts of deferred work haunt this new app?
Thank!

Worker dynodes work exclusively on tasks with a job delay.
If you don't have a delay job set, then you don't have to scale your employees counter (this is what DJ Jobs will take care of).
If you want to scale your web dynodes, just scale web = 2 or whatever you need.
I guess your mistake is that your newly changed DJ workers cannot find any assignments and they are wrong.
Worker scale = 0 and see if it fixes it.
And if you want to scale your web dynodes for better performance, web is what you are looking for.
