Comment 2

[Geoff Brown [:gbrown]]

This e10s-only failure happens mostly on linux32/64-opt but sometimes on other platforms.

Trying to find a regression range here: https://treeherder.mozilla.org/#/jobs?repo=autoland&filter-searchStr=e10s%20linux%20bc4&tochange=7927148d6726a6cb3751a5b3f8664fa9c6f5496d&fromchange=fffe9c114f88be787f003cdfe3d997d7d56b3081

https://treeherder.mozilla.org/#/jobs?repo=autoland&revision=7927148d6726a6cb3751a5b3f8664fa9c6f5496d is the first one I can find; it didn't repro in 10 linux-opt-e10s retries on any of the 5 previous pushes.

[Joel Maher ( :jmaher ) (UTC -8)]

Karolien, according to the retriggers on the range linked in comment 2, this failure started on your push from bug 1332952.  This is consistent on linux32/64 opt builds and only on e10s.

looking at a recent failure log[0], I see this in the failure:

here is the related screenshot to the failure:
https://public-artifacts.taskcluster.net/FMwTgS7BS-eNVfiYu5fvSA/0/public/test_info//mozilla-test-fail-screenshot_QHL03c.png

I suspect this is a failure to load the test case in the tab which is causing a failure, but that is just a guess.  Karolien, can you take a first look at this and see why your change might be causing this failure?

The test failed in the same way in a70d8500b13a, which was before 7927148d6726:

https://treeherder.mozilla.org/#/jobs?repo=autoland&filter-searchStr=e10s%20linux%20bc4&tochange=7927148d6726a6cb3751a5b3f8664fa9c6f5496d&fromchange=a70d8500b13a&selectedJob=75477712

This Linux e10s test will be disabled for bug 1331320 (due to bug 1237853) anyway.

this is disabled for e10s debug/asan:
https://dxr.mozilla.org/mozilla-central/source/browser/base/content/test/general/browser.ini#351

but this failure is opt primarily- should we disable this for e10s linux*?
