Hi Edwin, this is occurring on linux1804, is it something you can take a look at?

[Edwin Takahashi (:egao | infrequent contributor)]

There is another bug for this, bug 1607620.

I've pushed a fix that should be making its way through autoland at the moment.

I've updated bug 1607620 with reason for this failure. I'm working to green up the reftest-no-accel variant.
