I just updated the entries above to split them into three sections.

1. Flaky tests
2. Build related failures
3. Linter failures

@nodejs/build-infra PTAL at the jenkins issues.

[lundibundi]

I think parallel/test-worker-dns-terminate needs a stress test. It should be fixed based on nodejs/node#21327 (comment) and this PR nodejs/node#22189 no longer fails after rebase and this one nodejs/node#22198 fails but doesn't have a fix in it.
Local --repeat 1920 on linux box have also passed just fine.

[joyeecheung]

@BridgeAR By the way I think if the failure is caused by the --worker job (most test-packetnet-ubuntu1604-x64-2 failures there), it probably needs help from @nodejs/workers instead - and most of them are actually ENOENT under --worker so it could have something to do with how tmpdir resolves there.

[joyeecheung]

Closing because..there is no reason to keep it open?
By the way the --worker test failures reduced significantly these two days. I'll post the new results grabbed today.
