Firstly: there’s nothing in Sphinx, Thinking Sphinx or Flying Sphinx that uses Redis. The ts-sidekiq-delta and ts-resque-delta gems do because of Sidekiq and Resque, but that means you would already be using Redis.
Second: with Heroku, you want to use the fs tasks, not ts/thinking_sphinx tasks. So, try `heroku run rake fs:rebuild` instead?
If the problem still persists beyond that, can you run the task with the —trace argument and let me know what the stack-trace is?
