replicating process.send not working anymore. after a while messages sent from worker do not reach the master instance when under heavy load (~7000req/s).

gistfile1.js

var  cluster            = require( 'cluster' )
    ,http               = require( 'http' );

if ( cluster.isMaster ) {
    for (var i = 0; i < 8; i++) {
        var worker = cluster.fork();

        worker.on( 'message', function() {
            console.log( Math.random() );
        } );
    }
} else {
    http.createServer(function (req, res) {

        process.nextTick( function() {
            process.send( {} );
            console.log( process.pid + ': sending' );

            res.end( 'hello :) ' );
        } );

    } ).listen( 1337 );
}

Hi - did you ever figure this out?

actually no, but they seem to have fixed it: nodejs/node-v0.x-archive#3413
