When configuring Redis HA outside OpenShift for 3scale backend components according to the steps provided in the documentation (KCS), backend-worker and backend-cron deployments don't start. However backend-listener deployment starts successfully and redis data can be checked.

An example of the configuration of the environment variables to reproduce the issue is:

REDIS_QUEUES_SENTINEL_HOSTS: <IP1>:26379,<IP2>:26379,<IP3>:26379
REDIS_QUEUES_SENTINEL_ROLE: master
REDIS_QUEUES_URL: redis://mymaster/1
REDIS_STORAGE_SENTINEL_HOSTS: <IP1>:26379,<IP2>:26379,<IP3>:26379
REDIS_STORAGE_SENTINEL_ROLE: master
REDIS_STORAGE_URL: redis://mymaster/0

Where "mymaster" is the Sentinel group name.
