I see from the history that the test was re-written and the change committed a few days ago:

#14797

Fyi @eugeneo

[mhdawson]

Stress test to see if it can be reproduced in a number of runs: https://ci.nodejs.org/job/node-stress-single-test/1376/

I have a PR to mark it as flaky - #14874 - it is on the 48 hour cooldown, as per comitter guidelines.

It also fails on Windows, albeit differently.

[mhdawson]

Thanks for taking action quickly. I'd added another approval to the PR and I don't think we necessarily need to wait for the 48 hours so I started a CI run.

Is this something anyone is actively working on?

@nodejs/v8-inspector @nodejs/platform-aix Any chance we have a volunteer to dig more deeply into this? It's a pretty frequent occurrence right now.

I have submitted a potential fix. #15774
