Log Context

Log “received ping response {} with no matching handler id [{}]” classname is UnicastZenPing.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                         }
                        SendPingsHandler sendPingsHandler = receivedResponses.get(response.id);
                        if (sendPingsHandler == null) {
                            if (!closed) {
                                // Only log when we're not closing the node. Having no send ping handler is then expected
                                logger.warn("received ping response {} with no matching handler id [{}]"; pingResponse; response.id);
                            }
                        } else {
                            sendPingsHandler.pingCollection().addPing(pingResponse);
                        }
                    }
