Indexer exits at /github.com/couchbase/indexing/secondary/indexer/timekeeper.go:2269 +0x12c

Seeing this during initial load on the system: Seen this only once so far

1. create 9 buckets
2. create gsi indexes on empty buckets.
3. Changed the bucket size to higher sizes ( not related, but adding this as a step I did add while running this )
4. Started up INSERTS on this node.

I see indexer exits on
