Hot Rod JS client does not fetch all the data (misses)

Testing the Hot Rod JS client with sample Express apps sometimes the data is not fetched by the client (some misses in the stats).

We confirm that the data is always stored by the producer client, however the consumer client not always get all the keys. It is a low level of cases, but it is not valid at it is required to get all the values successfully stored in the cache.

For example here some screenshots for a simple use case putting and getting many different keys.

These values are confirmed with our client test script:

PS: We could not create this issue in the HRJS project, as GitHub repo informs, ... we don't have permissions there, or that project does not exit more.
