    Is there an existing issue for this?

    • I have searched the existing issues

    Current behaviour

    I opened a PR and the functional test failed https://github.com/bitcoin/bitcoin/pull/29500/checks?check_run_id=22324979545

    random seed: 2149187499175826776

    #29500 (comment)

    Expected behaviour

    I expected the test runner to pass

    Steps to reproduce

    Not sure how to reproduce other than running the test runner multiple times till it occurs

    Relevant log output

    https://github.com/bitcoin/bitcoin/pull/29500/checks?check_run_id=22324979545

    How did you obtain Bitcoin Core

    Compiled from source

    What version of Bitcoin Core are you using?

    master@f9ba6fd46d454d0a56662db751675a6520e1c9f6

    Operating system and version

    Cirrus CI / ASan + LSan + UBSan + integer, no depends, USDT

    Machine specifications

    This happened in the ci/cd

    If the process (bitcoind) is expected/allowed to open/close any files or sockets at any time, then this code is racy:

    https://github.com/bitcoin/bitcoin/blob/1105aa46dd1008c556b8c435f1efcb9be09a1644/test/functional/test_framework/netutil.py#L39-L40

    It may happen that listdir() will show an existent fd but by the time readlink() is called on it, it gets closed and is not in /proc anymore.

    Tentative fix, I did not try it as this is Linux specific:
