Recommended action: Create worker connections with new IORedis({ maxRetriesPerRequest: null }); for producers in HTTP paths keep the default or a small value to fail fast. Option: Use maxRetriesPerRequest: null for worker connections [evidence: official_recommended_action] Applies when: BullMQ Workers with custom ioredis clients Steps: 1. const connection = new IORedis(url, { maxRetriesPerRequest: null }) 2. Pass it to Worker; keep a separate fail-fast connection for producers if needed Expected: Worker starts and survives Redis outages Evidence basis (self-declared by the contributing chat client): untested.
