WebSocket connection is systematically terminated. Starting from version 1.1.12

[jsdavid]

System information

Geth version: v1.1.14 OS & Version: Debian-1011-buster-64-minimal

Expected behaviour

WebSocket connection should never drop. In version v1.1.11, the connection never dropped. I've been seeing this issue for a long time now. Please pay attention to this.

Actual behaviour

Starting from version v1.1.12, the WebSocket connection is systematically terminated

Steps to reproduce the behaviour

Run the following code through PM2 (preferably multiple processes), and watch the uptime. The connection may not break immediately, but after a long time.

import { ethers } from 'ethers'

const provider = new ethers.providers.WebSocketProvider('')
provider._websocket.once('open', () => console.log('Connection opened'))
provider._websocket.once('close', () => {
  console.log('Connection closed')
  setTimeout(() => process.exit(1), 0)
})

I'll attach a skin where 4 processes were launched at the same time. But in some processes, the connection was broken several times. (look at the uptime)
