Reason for failure (if possible)

The test fail is TestPlugin/too-many-translated-claim-parameters/prefilter

This failure may be caused by the error message's order sensitivity.

The error message's order of Resource Classes [default/my-resource-class default/other] versus [default/other default/my-resource-class] is different.

/remove-sig testing
/sig scheduling
(sig testing doesn't own all of the unit tests, just test frameworks, tooling, CI infra, etc)

This appears to be a flake in scheduler unit tests which would be sig scheduling (

kubernetes/pkg/scheduler/OWNERS

Line 4 in b503409

- sig-scheduling-maintainers

)

[BenTheElder]

.. and it appears to be DRA specific subset of scheduling so
/sig node
as well

FYI - looks like this is happening every 3-6 hours give or take. Yesterday it was every six hours and today it seems to be every 3-4 hours.

Looking into it a bit more, it looks like it may just be an issue with a connection via the test while it's trying to hit the server. I don't think the test itself is failing, I think the connection to the server is failing.

Hey All - hope you're well. Michael here from the Release Signal team.

Just wanted to touch base and make sure we're good to go for the cut on the 4th.
