WebRTC v2.0 start problem

[Artem_M_]

We installed v2 server as it was descrobed in manual.

We try to start it,But we faced with errors in woogeen-agent.stdout:

2015-01-17 19:13:53.670  - INFO: ErizoAgent - Terminate ErizoJS e0fa3ba0-0700-052f-4f50-db14eadfb3fc callback

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: spawn EMFILE
    at errnoException (child_process.js:1001:11)
    at Process.ChildProcess._handle.onexit (child_process.js:792:34)

And created a lot of files like erizo-feda4fe6-cfd6-cfc6-0075-800ba63a91ff.log

with content:

axconfig: port 1 not active
axconfig: port 2 not active

Previously we used version 1 and 1.5 - all was ok.

What should we do?

Hi Artem,

Thanks for your continuous support on our products!

Regarding the issue you mentioned, do you run v2.0 on the same machine that has been used for our v1.0 and v1.5?

If yes, then you need to restart MongoDB and RabbitMQ before launching v2.0.

[Artem_M_]

we tested on both examples:
on server where previously was 1 and 1.5 and on clean server.
To retest - we rebooted full server(where 1.5 worked) and tryed to start.

Start log:

One question regarding "sudo" in start operation, I think it will bring different behaviors from non-sudo mode. We recommend to start server without sudo privilege.

If issue still exists, please pack all the log files and upload to us for further analysis and verification. Thanks!

[Artem_M_]

In not sudo mode - test example starts, but video doesn't translating.

Log is in attachment.447103

woogeen-agent.stdout has error at the end:

in javascript error is in 

(woogen.sdk.js)

function e(a) {
                    b.call(this, a), this.isMixed = function() {
                        return !!a.video && "mix" === a.video.category
                    }, this.from = a.from
                }

a.video.category - is undefined

Started server is in http://46.182.24.175:3001/

It seems the axconfig error message comes from Node.JS. Could you share the node version you are using currently? Where do you download the Node.JS package?

In most case, axconfig error happens if you install node from sudo. In this case, uninstall node by sudo apt-get remove node... and reinstall the right version node without sudo.

[Artem_M_]

Thanks.You are right.
My WRANG way on installing nodejs was:

sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa:chris-lea/node.js 
sudo apt-get update
sudo apt-get install nodejs -y

The RIGHT way of installing node is:

#installing tools for NVM
sudo apt-get install build-essential libssl-dev

#downloading nvm
curl https://raw.githubusercontent.com/creationix/nvm/v0.16.1/install.sh | sh

#relogin the bash

#looking available versions
nvm ls-remote

#installing need version
nvm install v0.10.26


#start script
Release-v2.0/bin/start-all.sh

[Chunbo_H_Intel1]

Great to see the problem solved.
