javascript - Node.js / Socket.io raising Error at TCP.Onread -

i'm running simple node instance pushes data redis clients through socket.io.

my node server crashes time time. , i've spend hours in debugging, can't find problem.

it not predictable. instance runs fine 36 hours, sometime crashes every minute.

i receive following error message:

events.js:77     throw er; // unhandled 'error' event           ^ error: read econnreset     @ exports._errnoexception (util.js:676:11)     @ tcp.onread (net.js:529:26) 

this code:

var http = require('http'); var server = http.createserver().listen(4000);   var io = require('socket.io').listen(server);  var redis = require('socket.io/node_modules/redis'); var sub = redis.createclient(); var sc = redis.createclient(); //active socket counter  //subscribe redis chat channel sub.subscribe('chat'); sub.subscribe('total_spots');   io.sockets.on('connection', function (socket) {     //grab message redis , send client    sub.on('message', function(channel, message){        socket.send(message);    });       count++;     sc.incr("sockets");          socket.on('disconnect', function(socket){         count--;         sc.decr("sockets");     })         socket.on("error", function(err){        console.log(err);        console.log("error");     }); }); 

i appreciate tipps or ideas.

thanks!
