Flags: needinfo?(nchevobbe)
Regressed by: 1585012
Whiteboard: [retriggered][stockwell needswork:owner]

There are 61 total failures in the last 7 days, however none since the 8th of October.
Nicholas did you have the time to take a look?

I tried to have a look, but I wasn't able to fin the culprit in my patch.
I pushed to TRY with a rollback of my patch https://treeherder.mozilla.org/#/jobs?repo=try&revision=46b25c6b2fa446970418a4b6548f5b1d6b1051fb , but I'm not sure we can assert anything from it since you are saying it's been 3 days since the last test failure.

Flags: needinfo?(nchevobbe)

Yes, no occurrences since October 8th. I just wanted to know if you had fixed this and that's why the failures stopped.
Thank you.
