Couchbase View Indexing stuck at 100%

Couchbase Server
1

We have a Design Doc covering ~20M documents that has been stuck at Indexing: 100% for several hours. The same bucket has multiple other design documents that index properly.

Running CB 4.5.0 Community Edition. On 4.0CE this same view ceased to exist once its index hit 100%.

How can I debug this? Which log files might hold a clue? What is the cause of this issue?

Apparently there is some odd condition where an index will sit at 100% complete for a longer period of time before actually completing.

The index completed after another hour.
