I have an error creating a worker with Mediasoup 3.6.16

mediasoup libraries
1

Hello,

I have a server using “mediasoup 3.6.16”, on my local MAC computer it works without problems, but now I am trying to install it on a machine with Centos 6, to test it in a real environment,

System detail:
Node v10.23.0
Python v2.7.18
gcc y g++ v4.9.3
npm v6.14.8
Port: 9001 (open state)

I have no problem running npm install, but when I try to run npm start I get the following error:

root@aw0241 [/opt/mediasoup/server]# npm start

The error is occurring when trying to create a worker await mediasoup.createWorker({})

(async () => {
   await createWorkers()
})()
async function createWorkers() {
    let {
        numWorkers
    } = config.mediasoup
 
    for (let i = 0; i < numWorkers; i++) {
           
        let worker = await mediasoup.createWorker({
            logLevel: config.mediasoup.worker.logLevel,
            logTags: config.mediasoup.worker.logTags,
            rtcMinPort: config.mediasoup.worker.rtcMinPort,
            rtcMaxPort: config.mediasoup.worker.rtcMaxPort,
        })
        
        worker.on('died', () => {
            console.error('mediasoup worker died, exiting in 2 seconds... [pid:%d]', worker.pid);
            setTimeout(() => process.exit(1), 2000);
        })
        
        workers.push(worker)
        
    }
}

In the config, the cert.pem and key.pem are already configured

I hope to have your help, I have been all day trying to solve this problem.

PD: Sorry if it’s not well written, I don’t speak English, I’m using a translator.

thank you

I was have the same issue. And delete node_modules and run cmd ‘npm install’ to reinstall all modules solved this issue for me. I think this issue appear because i move all mediasoup server(include node_modules) from another ubuntu server to windows server.

If you don’t set the DEBUG environment variable properly (check the Debugging section in mediasoup docs) you won’t see the error.

I already tried to delete the node_modules folder and install again, but the error persists.

Cool. Now do what I said instead of any other random thing.

Now i ran it with the DEBUG enabled and it gave me the following

Thanks for the help, for me it was solved by installing the missing libraries

CXXABI_1.3.8
GLIBCXX_3.4.18
CXXABI_1.3.5
GLIBCXX_3.4.14
GLIBCXX_3.4.15
GLIBCXX_3.4.20

With this the service started correctly,

now I’m going to check the link you shared with me “Crashes in mediasoup (get a core dump)”,

Thanks for your help,
