Comment 18

[Serban Stanca [:SerbanS]]

It started to fail more often than before somewhere in this area but because the builds were busted I can't say exactly which changeset triggered this.
Hi Emilio! Could you please take a look at this? Could this be triggered by the changeset from Bug 1949742?
Thank you!

Comment 19

[Emilio Cobos Álvarez (:emilio)]

I'd say either bug 1949668 or bug 1949742, but in both cases it's likely to be pre-existing. DJ mind taking a look?
