cannot open more than 2 clients in the same script

[kapouer]

Hi,
blindy opening three clients in a simple node script will make two of them fail.
Opening two clients succeeds.

Any idea ?

It's subtler :

When MAX > 2 there are two clients that times out after the connection is opened.
Edit: much more clients fails to open a connection and get a message when MAX is higher (50)

Note that launching multiple (dozens) of those scripts with MAX=2 succeeds perfectly.

And it happens only within node. I just opened and exchanged messages with 4 eio.Socket from the same page on chromium browser, no problem.

Did you find out more about this?

if i do a naive install of engine.io@f2ffc527 + engine.io-client@78f2471e29, i get :

/home/dev/tmp/eng/node_modules/engine.io/node_modules/websocket.io/lib/protocols/hybi-16.js:39
    .on('text', function (packet) {
     ^

so i can't tell for now. Using node 0.6.19.

Yeah sorry I had to fix ws to an older version because @einaros changed that API

Ok then, using engine.io-f, engine.io-client-f :

With MAX=1, and waiting one minute :

opened 0
opened 1
received 0
received 1

With MAX=2, waiting one minute :

opened 0
opened 1
received 0
opened 2
received 1
received 2
close ping timeout

The last line appears after quite some time.

This is so stupid of me :
http://nodejs.org/docs/v0.6.19/api/http.html#http_agent_maxsockets

So this fixes the issue in client.js i give in the example :

require('http').globalAgent.maxSockets = 20;
