redis-py 8.0 changed the default socket_timeout from None to 5s when using the Redis() constructor directly. ckanext-harvest's get_connection_redis() uses the constructor when ckan.harvest.mq.hostname is set, giving the gather and fetch consumer pods a 5s socket timeout on their Redis connections. BLPOP blocks waiting for harvest jobs — with no jobs in queue it exceeds the 5s socket timeout immediately, crashing the pod with: redis.exceptions.TimeoutError: Timeout reading from socket The fix: remove the mq.hostname/port/redis_db settings from the configmap. Without mq.hostname, ckanext-harvest falls through to Redis.from_url() using ckan.redis.url (already set), which preserves socket_timeout=None and allows BLPOP to block indefinitely as intended.

@amar-gds-ndl let's hold off a bit on this as there's a bit more digging needed

I have now fixed that by removing the mq.hostname/port/redis_db settings from the configmap. Without mq.hostname, ckanext-harvest falls through to Redis.from_url() using ckan.redis.url (already set), which preserves socket_timeout=None and allows BLPOP to block indefinitely as intended.
