Comment 1

[Chris Martin [:cmartin]]

I'm investigating this. I'll see if I can fix it quickly without a backout.

Comment 2

[Chris Martin [:cmartin]]

I wasn't able to figure out what went wrong here. Please back out.

Comment 3

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Not convinced this is a regression from bug 1909470 - will verify with a backout on Try tomorrow.

Comment 4

[amarc]

After backing out bug 1909470 on Try on the latest central as beta simulation , looks like the failure's still there.

Looking at https://treeherder.mozilla.org/intermittent-failures/bugdetails?startday=2025-01-30&endday=2025-03-01&tree=all&failurehash=all&bug=1822337 this has been failing for a while now, first failed on beta-sims here and failed as a TV on the original push on autoland. Only devedition and shippable runs are affected on macOS 10.15.
Andreas, could you have a look over this one? Thanks.

[Andreas Pehrson [:pehrsons]]

These are all in the dtls tests and predate bug 1942640. The rate appears to have gone up with bug 1942640 but unclear what the root cause is. Might be timing. Byron can you take a look?

The bug is marked as tracked for firefox137 (beta). However, the bug still isn't assigned.

:jimm, could you please find an assignee for this tracked bug? Given that it is a regression and we know the cause, we could also simply backout the regressor. If you disagree with the tracking decision, please talk with the release managers.

[BugBot [:suhaib / :marco/ :calixte]]

This is a reminder regarding comment #8!

The bug is marked as tracked for firefox137 (beta). We have limited time to fix this, the soft freeze is in 14 days. However, the bug still isn't assigned and has low priority.

Comment 12

[Byron Campen [:bwc]]

I have a feeling that this is being caused by prior tests whose PCs are still doing DTLS handshake stuff while closing. Moving the DTLS handshake tests first ought to compensate for this.

Comment 13

[Byron Campen [:bwc]]

So far, so good. The same jobs in the description did not run however, so I've added them. We'll see how it goes.

Comment 19

[BugBot [:suhaib / :marco/ :calixte]]

The patch landed in nightly and beta is affected.
:bwc, is this bug important enough to require an uplift?

• If yes, please nominate the patch for beta approval.
• If no, please set status-firefox137 to wontfix.

Comment 20

[Byron Campen [:bwc]]

Is the current beta actually affected by this?

Comment 21

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Yes, classifications are against bug 1822337. Log of a failed beta task.

Comment 22

[Byron Campen [:bwc]]

I can't find anything on beta on orangefactor. Is this common enough to make it worth a beta uplift?

Verified fixed in today's central as beta simulation.
