=== Failed
=== FAIL: transport TestWriteReadTimeoutListener (0.01s)
    timeout_listener_test.go:113: err = EOF, want write i/o timeout error

It maybe a flaky test case.

Let me mark it as draft.

Seems reproductionable. Failed again:

Great work.

Thanks for identifying the root cause of #14487

Still working on the failed test case. It is weird. I can't reproduce it in my local. I was thinking that the connection is closed. Let me file issue to track this.

Due to different environment GitHub actions CI frequently flakes on issues that are hard to reproduce locally. I suspect this is due to limited resources, especially CPU. I think you could try to emulate it locally.

Yeah. For sure. I am trying to run it limited-resource vm.
