MaxListenersExceededWarning in 9.0.1 #510
Description
Hi,
I am using node v18.16.0 with concurrently v9.0.1
After calling concurrently few times with 20-30 commands I am getting this warning:
(node:3690238) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 SIGINT listeners added to [process]. Use emitter.setMaxListeners() to increase limit
at _addListener (node:events:587:17)

at concurrently (/var/node/node_modules/concurrently/dist/src/index.js:48:44)
The code sequence I am using is this:
function test(commands){
var mockedStream = new PassThrough();
const { result } = concurrently(
commands,
{
outputStream:mockedStream,
prefixColors:false
},
);
result.then((res)=>{
console.log(res);
}, (res)=>{
console.log(res);
});
}_
The commands array is looking as follows:
_[
'sshpass -p admin ssh -o "UserKnownHostsFile=/dev/null" -o "StrictHostKeyChecking=no" -o ConnectTimeout=7 admin@10.72.107.88 << EOF\n' +
'version\n' +
'EOF',
'sshpass -p admin ssh -o "UserKnownHostsFile=/dev/null" -o "StrictHostKeyChecking=no" -o ConnectTimeout=7 admin@10.131.253.212 << EOF\n' +
'version\n' +
'EOF',
'sshpass -p admin ssh -o "UserKnownHostsFile=/dev/null" -o "StrictHostKeyChecking=no" -o ConnectTimeout=7 admin@10.131.253.210 << EOF\n' +
'version\n' +
'EOF',
'sshpass -p admin ssh -o "UserKnownHostsFile=/dev/null" -o "StrictHostKeyChecking=no" -o ConnectTimeout=7 admin@10.131.253.21 << EOF\n' +

'EOF',
'sshpass -p admin ssh -o "UserKnownHostsFile=/dev/null" -o "StrictHostKeyChecking=no" -o ConnectTimeout=7 admin@10.131.253.211 << EOF\n' +

'EOF'
