Comment 1

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

This seemed to start with bug 1393119 - 175 retriggers before that did not fail (and the chunk contains the test), but the backout didn't fix it: https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&group_state=expanded&filter-resultStatus=testfailed&filter-resultStatus=busted&filter-resultStatus=exception&filter-resultStatus=retry&filter-resultStatus=usercancel&filter-resultStatus=runnable&filter-resultStatus=success&fromchange=d246d499d9a596392d7a793e8d8033fd52ee2dd6&filter-searchStr=mda2%20linux%20stylo%20debug&tochange=39ec8854eb67bf1badb9439363173b970b44bf0b

Failure after the backout: https://treeherder.mozilla.org/logviewer.html#?job_id=158124447&repo=mozilla-inbound

Dan, any clue what's going on with that test? Thank you.

Comment 2

[Dan Minor [:dminor]]

If it is still happening after the patches were backed out, it seems unlikely that the patches caused the problem, but perhaps they made an already present intermittent much more frequent. I'll do some local testing.

Comment 3

[Dan Minor [:dminor]]

This is a try run with the gn patches attached:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=24be9379ca28641c4732f6cde94eecee0a5fbbc4

This is a try run with just the parent commit of the gn patches:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=586371f89464d005bdb6ea52ccb999e1fdfb01d4&selectedJob=158211392

We ended up with one hit each in 206 runs across opt and debug in both conditions. Given that the frequency seems to be approximately equal with or without the gn patches, I think it was just a coincidence that this showed up when those changes landed. I think this shouldn't block relanding the gn patches.

If this ends up being a high frequency intermittent I'll be happy to investigate further.

Comment 4

[Dan Minor [:dminor]]

Nico, any thoughts on this one?

Comment 5

[Nico Grunbaum [:ng, @chew:mozilla.org]]

I don' think the failure is related to the gn patches. It is more likely to be a timing issue with the test. I will take a look. Retaining NI.

Comment 6

[Nico Grunbaum [:ng, @chew:mozilla.org]]

So far all failures are on linux, and all but one is a debug build.
