No response randomly when DEV on Node v14 & v15

[Cow258]

Bug report

Describe the bug

Should be backend issue.
Only happen when using Node.js v14/v15.
Only happen when the build take time that about half second or more.
Only happen when development mode.
No issue when using other version of Node.js.
No issue when production and static export.

No response when routing to some page that not yet built by hot-reload server.
The .js file will keep waiting response.
But Next.js console shown

event - build page: /some/issue/page
wait  - compiling...
event - compiled successfully

Then when you type the .js url of the issued page into browser on new tab,

127.0.0.1:3000/_next/static/chunks/pages/some/issue/page.js

It still no response and waiting response.
After waiting about 1min,
Next.js console shown again

event - build page: /some/issue/page
wait  - compiling...
event - compiled successfully

Then the url will response normally.
But when you back to the app,
The page still unable to reach without refresh.

So I need keep refresh many times to test some simple things.
Or downgrade to Node.js v12.

To Reproduce

I'm still making a repo that can 100% reproduce this issue,
But it is hard,
Coz this issue happen so randomly,
If the bundle size too small, it can't happen.

Any way,
Here are some screen record,
Hope helpful.

No response

When .js keeping no response and keep clicking the link to that page.

Keep no response after refresh

Some case, refresh is useless.

Click another link to make it work

Links
> A: Some link no yet build since server boot up
> B: The link you want to got to

1. Click A link first
2. Click B link
3. When B link will work
4. But A link will still no work
   (If you want A link work, refresh and click B link first)
   

Expected behavior

The bundle .js file should response when built.

System information

• OS: Any
• Browser: Any
• Version of Next.js: > 9.5.0
• Version of Node.js: v14 / v15

Additional context

Remember!
All working when using Node.js v12.
All working when production and static export even if Node.js v14/v15.
Any thing and any code is working well.

I hope the above information is helpful.

Feel free to ask me for more information.

Thanks.
