May memory leak in 0.24.0.

[pingfengafei]

Describe the bug

I've write a tool which uploads large (may more than 10GB) and multiple files to AWS S3 in browser, and met memory leak.
Each http request put chunk at 5MB and the ArrayBuffer should GC. however:

First with 0.21.4, memory always leak and there is an issue: #3694, and then updated to 0.24.0. after that, local env (macbook pro) works well but My QA env has a quite strange behavior.

First step, Every time upload success.
Second: Upload failed with memory leak in much chance, and upload success in a few chance.
Third: the Second reversed.

I can not reproduce this behavior in my local, anyone met the same issue?

besides, the #3694 related issue fixes follow-directs error, but it is used in Node, why effect browser?

Environment

• Axios Version [0.24.0]
• Adapter [HTTP]
• Browser [Chrome, Safari, Firefox]
• Browser Version [may latest or newly version]
• OS: [11.6.1]

Seeing the same issue. We are doing POST requests every 10 seconds and it looks like the request body is not being released. We have isolated it down to nothing but the HTTP POST through axios.

I'm also observing a memory ramp up when issuing subsequent POST requests to different URLs. I boiled the issue down to the following problematic code:

The memory just keeps ramping up... After no more POST requests are issued, the memory is released at some point, but it may take up to 10 minutes for it to take effect.

When all POSTS are issued to the same URL (fix run and i in the above code to constant values), the issue disappears.

I'm observing this on React-Native v0.64.3 and axios v0.25.0.

This is the ramp-up I observe:

When POSTing to the same URL repeatedly, the ramp up (mostly) disappears:

Hi 👋

Please could you retry with the latest version and open a new issue should this error still be relevant?

Thanks
