Simultaneous writing are skipped (3 and more)

Hello,

I have an issue with an express API when multiples request are processed in the same time, there are not all logged (rotating-file-stream: 2.1.4).

Here is a sample code:

  const accessLogStream2 = rfs.createStream('access-test.log', {
    interval: '1d',
    path: path.join(__dirname, 'log'),
    teeToStdout: true,
  })

  api.use((req, res, next) => {
    console.log(`console ${Date.now()} ** ${req.url}`)
    accessLogStream2.write(`rfs ${Date.now()} ** ${req.url}\n`)
    next()
  })

And here is the output:

console 1612715099666 ** /api/states?module=srm&logicalId=devices
console 1612715099667 ** /api/states?module=srm&logicalId=eth0-upload
console 1612715099669 ** /api/states?module=srm&logicalId=lbr0-upload
console 1612715099670 ** /api/states?module=srm&logicalId=eth0-download
console 1612715099671 ** /api/states?module=srm&logicalId=lbr0-download
rfs 1612715099666 ** /api/states?module=srm&logicalId=devices
rfs 1612715099667 ** /api/states?module=srm&logicalId=eth0-upload
...
console 1612715099691 ** /api/states/165
console 1612715099692 ** /api/states/168
console 1612715099692 ** /api/states/166
console 1612715099693 ** /api/states/169
console 1612715099694 ** /api/states/167
rfs 1612715099691 ** /api/states/165
rfs 1612715099692 ** /api/states/168

It seems that only 2 logs are logged 😞 Any idea?

It seems the problem is with Node.js v14, using it I have the same problem. On v12 the script works as expected. I’ll try to fix this

Thanks @iccicci, seems to be fixed 👍🏻
