Not receiving all messages

• OS: Google Container Engine (Kubernetes)
• Node.js version: gcr.io/google_appengine/nodejs
• npm version:
• @google-cloud/pubsub version: 0.16.2

I have a very simple subscription on a topic that runs in Container Engine. The code is the same as your examples:

const pubsub = require('@google-cloud/pubsub')();

const projectId = process.env.GOOGLE_CLOUD_PROJECT;
const topic = pubsub.topic('projects/' + projectId + '/topics/security-logs');
const subscription = topic.subscription('projects/' + projectId + '/subscriptions/securitySubscription');

subscription.on('error', function (err) {
    "use strict";
    console.error("Subscription error: " + err);
});

function onMessage(message) {
    "use strict";
    // Called every time a message is received.
    logger.log("Subscription message received: " + JSON.stringify(message));
    const data = Buffer.from(message.data).toString('utf-8');
    logger.log("message.data: " + data);
    message.ack();
}

subscription.on('message', onMessage);

The problem is that not all messages are received. I would say a little more than 50% are.

I see in my logs that messages are successfully sent by publishers (I get messageIds) but the subscription does not get them all. I have only one subscriber.

Any idea what might be wrong ?
