:overholt does anything stand out in the regression range? This is averaging around 5 crashes per day, which is not super large volume.

Let me look at the range.

Comment 3

[Olli Pettay [:smaug][[e-mail]]]

So far I haven't found anything suspicious.

Comment 4

[Olli Pettay [:smaug][[e-mail]]]

Went through the range again, and couldn't see anything there.

looks like this is a continuation/signature change of bug 1430813.

[Liz Henry (:lizzard) (relman/hg->git project)]

There is 1 crash on 61.0.2 in the last few days, so maybe there is some lingering issue. Based on the status in the duplicate bug I'll call this fixed in 61 though.
