    new in this release. Pings are used for connections that are busy carrying
    calls and for idle connections in the connection pool. (Pings do not impact
    when pooled connections are evicted).

    If you have a configured ping interval, you should confirm that it is long
    enough for a roundtrip from client to server. If your ping interval is too
