query service fails to see a collection

Intermittently, the query service will fail to see a collection that exists. 

In this test, 1000 collections are created and loaded with 20,000 docs and then the following query is run for different random keys and different random collections: 

SELECT * FROM default:`bucket-1`.`scope-1`.`collection-1` USE KEYS[$1]; 

The sdk attempts to prepare this query for each collection. Query service returns an error for one of the queries:

SELECT * FROM default:`bucket-1`.`scope-1`.`collection-521` USE KEYS[$1];

{
"errors": [

{ "code": 12003, "msg": "Keyspace not found in CB datastore: default:bucket-1.scope-1.collection-521", "query_from_user": "explain SELECT * FROM default:`bucket-1`.`scope-1`.`collection-521` USE KEYS[$1];" }

]
}

However, collection-521 exists and all other queries on different collections work fine.
