问题
I have an error I cannot find any information on. This is a Ruby on Rails stack (Ruby 1.9, Rails 3.2) and using sqlite3 database for development. Resque and Redis are used for background jobs. The rails web application starts up fine and can access and update the database. I can login with sqlite browser and see records and run queries. The issue is any Resque job cannot access database, and gets an I/O exception. I can see the jobs on the resque web browser/queue and retry them but they still fail. Any help is greatly appreciated, thank you.
