Seeing "Exceeded retries count trying to get consistent keys/values for config replication"

Build: 6.6.1 build 1000012378

Scenario:

• Cluster with 5 kv, 2 index+n1ql, 2 search nodes
• 6 bkts with 5000 docs each
• Built 200 GSI indexes with replica 1 (50 indexes on 4 buckets)
• Created 30 fts custom indexes (10 indexes on 3 buckets), just to add more entries to metakv
• Create and Drop 100 gsi indexes sequentially on 4 buckets ( so this would be adding more entries of create/drop of 400 indexes)
• Create and drop 50 fts indexes on 3 buckets.

After step#6, seeing below prints in the logs,

Exceeded retries count trying to get consistent keys/values for config replication. This is minor bug. Everything is safe, but please file bug and attach logs
