title: AbortError: Ready check failed: Redis connection lost and command aborted. It might have been processed
body: <p>What does this error message means and what are the possible causes for it? I'm using node 6.10.0 and redis 2.7.1. I run Redis store in separately Docker container and the container is successfully built. After that I prime the store with access tokens that I need in my application. I do it with script and at that moment I get the error message.</p>
