Dao, this has now reached the disable recommended threshold with 133 failures in the last 30 days, could you please take a look over this or redirect to someone? https://treeherder.mozilla.org/intermittent-failures.html#/bugdetails?startday=2019-06-08&endday=2019-07-08&tree=trunk&bug=1549985

Hey Cosmin, I am curious which commit makes the test failure frequent. Did somebody in your team narrow the range down? I know some of patches in bug 1488953 makes the test failure less frequent but they were backed out (https://hg.mozilla.org/mozilla-central/rev/91c42888cf7f).

Flags: needinfo?(csabou)

Hiroyuki, looking at — Orange Count — Push Count graph from here https://treeherder.mozilla.org/intermittent-failures.html#/bugdetails?startday=2019-05-20&endday=2019-07-08&tree=trunk&bug=1549985 it looks like it had a steady low failure rate until the landing of Bug 1488953 here https://tinyurl.com/y2se7y32 but with that being backed out 11 days ago the failure rate is now again steady at around <10 failures/day. It's a pretty hard one to track down exactly with retriggering and backfiling cause it often changes chunks, browser-chrome-e10s-9 browser-chrome-e10s-10, browser-chrome-e10s-2 and so on... More often that not it fails on linux64 asan and debug. I wish I could have a more straightforward answer to this.

Flags: needinfo?(csabou)

Thanks, so I was thinking some of patches for the test case in bug 1488953 made the test less frequent, but now I think they are not sufficient. And I know the peak of Jun 26 was caused by bug 1559690 which was also backed out.

Given the original spike came from bug 1488953, I guess hiro or emilio would be the best person to dig deeper. Hiro, are you aware of other layout changes from the last few weeks that could have contributed here?

I also wonder if this started happening with some specific changeset two months ago but I guess the failure rate was too low to figure this out.

Flags: needinfo?(dao+bmo) → needinfo?(hikezoe.birchill)

Good question. I wasn't aware of any suspicious commits, so I did a quick skim around July 5th. There was a suspicious commit (by me) which is bug 1562757, and I did a bunch of retriggers on the commit, it turned out it's not the culprit.

Then I did also retrigger other changeset and found the commit in question. There is no commit related to layout stuff. I wouldn't be surprised that Kris' commits in the changeset might affect this test failure.

Anyways, for now I am going to land D33614 and D33615 (in bug 1488953) that I believe it mitigates the test failure to some extent. Let's see whether it mitigates or not.

The test was only added two months ago in bug 1543607 so this answers that question.

In comment 18, hiro said he'd land patches to improve this test so you probably want to revert the above?

I hoped so, but it looks it didn't change at all (even worse?)

Hi Dão, since the disable was backed out, are you working on a fix here?

Comment 25 mentions that there are no improvements from the already landed patches.

Hi Joel, any insight on how to move forward with this bug?

Flags: needinfo?(jmaher)

:apavel, this meets our threshold for disable-recommended, please disable the test again.

To re-enable this we need to fix the test and land code that specifically re-enables this (ideally with a fix to the product or test case), not backing out the disabling patch. Even if there is a patch waiting on review, it is easy to re-enable a test. 30+ failures/day is not healthy and is one of our most frequent failures on the tree.

Dao, any insights what causes this intermittent failure on macOS?

(In reply to Sebastian Hengst [:aryx] (needinfo on intermittent or backout) from comment #58)

Dao, any insights what causes this intermittent failure on macOS?

No idea. Has this recently started failing on macOS when it previously would work reliably there?

Flags: needinfo?(dao+bmo) → needinfo?(aryx.bugmail)

There was a spike on last week. The macOS failures are actually pre-existing, the ones on Windows are new. Most of them are for or after bug 1633635 landed except one Windows failure which occurred earlier.

Flags: needinfo?(aryx.bugmail)
Flags: needinfo?(dao+bmo)

In the last 7 days there have been 31 occurrences on windows7-32, windows10-64, macosx1014-64 build types asan, debug and opt.
