Comment 1

[Cristian Tuns]

Hello Emilio, can you please take a look at this to see if this might be caused by one of your changes?

• backfills

Comment 2

[Emilio Cobos Álvarez (:emilio)]

By which change are you suspecting? It doesn't seem likely off-hand.

Comment 3

[Cristian Tuns]

After the backout of Bug 1767172 looks more frequent, but it's just a guess.

Comment 4

[Emilio Cobos Álvarez (:emilio)]

Yeah that's ~impossible I think. But anyways I just queued that bug for landing again so if it was that you'd see the intermittent stop.

Comment 5

[Cristian Tuns]

This should be fixed by backout of Bug 1767514: https://hg.mozilla.org/integration/autoland/rev/f138b7007901b9b46337fe27496be0810016e20c
