Mike, could you help us assign this to someone?
Thank you.

This is permafailing on Linux 18.04 x64 Shippable.
Chris, will the annotation be further updated on Bug 1713900, or should it be done individually on this one?

(In reply to Alexandru Michis [:malexandru] from comment #40)

Chris, will the annotation be further updated on Bug 1713900, or should it be done individually on this one?

I don't know how soon bug 1713900 will fix the root cause of these test failures. If you can update this test's annotations to skip Linux in this bug (changing fission && (os != "linux" || asan) to simply fission), that would be helpful.

The SHIP permafail will be fixed in bug 1715264. We should keep this open as the intermittent happens without Fission as well.

Andreas, this browser-chrome test for Session Store is failing a lot (30–40 failures per week, enough to warrant a [stockwell disable-recommended] whiteboard tag) for Fission on Linux. Can you (or Kashav?) take a look before the test sheriffs disable the test?

The test was fixed in bug 1715264, which landed earlier today!

Awesome! I'll optimistically close this bug as fixed by bug 1715264.

(In reply to Intermittent Failures Robot from comment #51)

21 failures in 621 pushes (0.034 failures/push) were associated with this bug yesterday.

That's a lot of failures for one day! We're hoping bug 1715264, which landed yesterday, will fix them. Let's wait to see if there are any more failures with today's build.

No failures since bug 1715264 got merged: https://treeherder.mozilla.org/intermittent-failures/bugdetails?startday=2021-06-04&endday=2021-06-11&tree=trunk&bug=1536528

Started failing again here: https://treeherder.mozilla.org/logviewer?job_id=343383287&repo=autoland&lineNumber=11237

Appears to be without Fission. See comment #45.

(In reply to :kashav from comment #56)

Appears to be without Fission. See comment #45.

In that case, I will clear this bug's Fission Milestone so it doesn't block Fission MVP.
