When Redis is down an error happens and cleanup signal is trying to update things in Redis, which throws.
As a result, the unhandled exception is caught by handler that will attempt an cleanup again with same results, endless loop, maybe... so I wrapped the cleanup handler in try/catch block so that the process is effectively terminated and it can be collected by the container and restarted.
