Hi Matteo, first off great job :) I'm just playing around with mosca following getting started with mqtt when I run (localhost) this simple code:

var mosca = require('mosca')

var pubsubsettings = {
  type: 'mongo',
  url: 'mongodb://localhost:27017/mqtt',
  pubsubCollection: 'myCollections',
  mongo: {}
};

var settings = {
  port: 1883,
  backend: pubsubsettings
};

//here we start mosca
var server = new mosca.Server(settings);
server.on('ready', setup);

// fired when the mqtt server is ready
function setup() {
  console.log('Mosca server is up and running')
}

// fired whena  client is connected
server.on('clientConnected', function(client) {
  console.log('client connected', client.id);
});

// fired when a message is received
server.on('published', function(packet, client) {
  console.log('Published : ', packet.payload);
});

// fired when a client subscribes to a topic
server.on('subscribed', function(topic, client) {
  console.log('subscribed : ', topic);
});

// fired when a client subscribes to a topic
server.on('unsubscribed', function(topic, client) {
  console.log('unsubscribed : ', topic);
});

// fired when a client is disconnecting
server.on('clientDisconnecting', function(client) {
  console.log('clientDisconnecting : ', client.id);
});

// fired when a client is disconnected
server.on('clientDisconnected', function(client) {
  console.log('clientDisconnected : ', client.id);
});

I've got

Mosca server is up and running terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc Aborted

I've read this issue is due to a lack of memory but I've got 4GB ^^

So can you help me, please ?

Have a good day :)

Which OS are you using? Which other applications are you running at the same time? Currently test.mosca.io runs in a VPS with 512MB of RAM, so definitely there is something else going on.

btw with redis it works fine.

Thanks for the quick reply.

mcollina commented 9 years ago

which version of node.js are you running? what are client2 and server1, that I can see in your ps report?

BTW, it seems you are running out of memory, if we count that you have LOTS of tabs of Chrome open, firefox, apache and mongodb.

Finally, it seems you are running mosquitto on your system, which means you need to change the Mosca port, or you won't be able to start it.

BTW I'm looking for good tutorials and guide on the topic.

mcollina commented 9 years ago

And you still can't run the server? Can you please try running the executable (npm i mosca -g; mosca).

I don't exactly know good tutorials on the topic. I never run Linux Mint, and Mosca have no problem running on generic Linux, so something else might be going on.

whisher commented 9 years ago

Yes, I can run mosca. Ok it doesn't matter may be my localhost has something wrong. You can close the issue I reopen it if I find problem in the server dev/prod. Thanks
