[alyssawilk]

normally I don't post from open PRs but I can't see how a file move is relevant to failure so I think this one's real

hitting this on the 1.26 release branch

[paul-r-gall]

This should have been fixed by #26605 -- is that PR included in the 1.26 branch? I don't know how to tell.

[phlax]

you can see on the commit that landed 4b730e4

it shows the tags that include it, with the caveat that it doesnt include backports - in this case its there

[paul-r-gall]

@phlax what compilation tags should I be running with to get a repro? and what's the frequency you're seeing?

[phlax]

what compilation tags should I be running with to get a repro?

there are some docs here worth checking https://github.com/envoyproxy/envoy/blob/1b906296c2525e9898b9880f0b6be0ed52003b17/test/integration/README.md#deflaking-tests

what's the frequency you're seeing?

not high altho, i think there was at least one on postsubmit today

https://dev.azure.com/cncf/envoy/_build/results?buildId=135895&view=logs&j=767be981-567e-57d8-68c3-2140ede0a0bd&t=67a76341-37f4-5b49-db38-acbb8a59af82&l=954

[paul-r-gall]

The failure you linked above is IpVersionsAndStreaming/ShadowPolicyIntegrationTest.Basic/IPv6_streaming_shadow, not RequestMirrorPolicyWithShadowOnlyTimeout. It ought to be fixed by #27126.

[phlax]

thanks

ill test backporting it tomorrow

unfortunately i didnt post the link when i hit it on the 1.26 branch and i think it was in presubmit/pr so harder to find, so not sure exactly the error there

[phlax]

closing this - i have backported whatever would pick easily and im not seeing this issue on main or release branches
