What is the current behaviour?

After updating my Webpack and Testcafe version I am getting an error named ECONNRESET. Testcafe runs against a webpack-dev-server an executes the tests, at least some of them. After some time testcafe dies with this error message:

Error: read ECONNRESET
    at TCP.onread (net.js:660:25)
Emitted 'error' event at:
    at Socket.onerror (_stream_readable.js:687:12)
    at Socket.emit (events.js:182:13)
    at Socket.EventEmitter.emit (domain.js:442:20)
    at emitErrorNT (internal/streams/destroy.js:82:8)
    at emitErrorAndCloseNT (internal/streams/destroy.js:50:3)
    at process._tickCallback (internal/process/next_tick.js:63:19)
### How would you reproduce the current behaviour (if this is a bug)?

I already found an issue (#2649) but it does not help me. Seems to me like there are sometimes issues with closing a connection when ending a fixture. I already tried using the Node version v10.5.0 but does not help so far.

What is the expected behavior?

The tests run through.

Specify your

• operating system: macOS High Sierra v10.13.6
• testcafe version: v0.21.0
• node.js version: v10.8.0
