    Status update: I am looking into it but this seems to be an actual bug (console.log is not reported to the front end randomly) and not just a test issue. Looks like other platforms do not see this, on CentOS there was 1 failure out of 100 runs.

    I don't know how long it will take to fix this... Should I mark the test flaky for now?

    I saw this again today, on CentOS 5 as usual. I guess we can add this as another data point for "something is up with CentOS 5, it's EOL anyway, let's remove it from CI". See nodejs/build#898

    Alas, saw this on ubuntu 1604-32:

    This test is now in sequential and has a slightly different name. Seems likely it's not flaky anymore. Closeing.
