MESSAGE_TYPE.CONNACK endless loop

[nakvic]

Once connection established, paho client executes onSuccess callback endlessly, that is the following part of code is executed over and over again (paho-mqtt.js:1269):

case MESSAGE_TYPE.CONNACK: this._connectTimeout.cancel(); if (this._reconnectTimeout)

However, server sends CONNACK only once: 1545401288: New client connected from <IP> as CLIENT-3331ad84-92c0-514f-a26e-c3c8fd186b76 (c1, k60, u''). 1545401288: Sending CONNACK to CLIENT-3331ad84-92c0-514f-a26e-c3c8fd186b76 (0, 0)

Browser: Chrome

Server: Eclipse Mosquitto 1.5.5

OS: Raspberry Jessie

Client js code:

`

host = <removed>;
port = <removed>
username = <removed>;
password = <removed>;
var client = new Paho.Client(host, port, "CLIENT-" + guid());

// set callback handlers
client.onConnectionLost = onConnectionLost;
client.onMessageArrived = onMessageArrived;

// connect the client
client.connect({
    onSuccess:onConnect,
    userName:username,
    password:password,
    useSSL:true
});

// called when the client connects
function onConnect() {
    // Once a connection has been made, make a subscription and send a message.
    console.log("onConnect");
}

// called when the client loses its connection
function onConnectionLost(responseObject) {
    if (responseObject.errorCode !== 0) {
        console.log("onConnectionLost:"+responseObject.errorMessage);
    }
}

// called when a message arrives
function onMessageArrived(message) {
    console.log("onMessageArrived:"+message.payloadString);
}

`

Hi everybody, Once connection established, paho client executes onSuccess callback endlessly, code is executed over and over again (paho-mqtt.js:1269):

I am stick also for several month I have exactly the same issue on firefox and on chrome either with my code or with Victor code, is it fixed? CPU 100% and high memory leakeage

My configuration: server: Eclipse Mosquitto version 1.5.6 starting, OS: is Debian version 8.11"jessie"

Browser: Firefox developer edition 68.0b4 (64-bit) os: windows 10

Thanks to all by advance! Jean-Philippe

here is my code, but same result with Josh code ========= MY CODE ============== var client = new Paho.MQTT.Client("10.8.0.1",Number(9001),"/test","test"); // set callback handlers client.onConnectionLost = onConnectionLost; client.onMessageArrived = onMessageArrived;

// connect the client client.connect({onSuccess:onConnect}); // try to fix by : client.connect({onSuccess:onConnect,mqttVersion:3}); => same issue

// called when the client connects function onConnect() { // Once a connection has been made, make a subscription and send a message. console.log("onConnect"); // => Endless loop on this connect client.subscribe("#");// Doesn't depend if commented or no }

// called when the client loses its connection function onConnectionLost(responseObject) { if (responseObject.errorCode !== 0) { console.log("onConnectionLost:"+responseObject.errorMessage); } }

// called when a message arrives function onMessageArrived(message) { console.log("onMessageArrived:"+message.payloadString); }

I noticed Im having this issue too, presumably after CloudMQTT (my broker provider) updated their Mosquitto version? Everything worked fine before that.

Funny enough, even the CloudMQTT website displays this behavior.
