Issue/Introduction

I have these periodic WARN in doi-normalized-alarm log.

2025-###-### 11:36:36,146 [DiscoveryService,hz.focused_shirley.cached.thread-6] WARN  - [###.###.###.###]:5701 [normalizedalarmservice] [5.5.0] DNS lookup for serviceDns 'doi-normalized-alarm-hazelcast-cluster.###-###-###.svc.cluster.local' failed: unknown host

There is no such service doi-normalized-alarm-hazelcast in DX OI deployment. Why it try to resolve it, or why is this service not defined in deployment? Shall I be worried about this warning?
