Status: RESOLVED INCOMPLETE

Description

[Marcia Knous [:marcia]]

This bug was filed from the Socorro interface and is
report bp-1c736932-a5bc-407a-88f8-fc04c0181119.
=============================================================

Seen while looking at 64 crash stats: https://bit.ly/2DCcARJ. Although present on release, 64.0b9 crash rate seems to be increasing and is approaching the same number of crashes as 63.0.2 release. APIs from 28 down to 19 are affected. Pixel 2 and Pixel 2 XL devices are in the affected list. 65 does not appear to be affected.

ni on Eitan as I think he is doing some work in 65 in this area. Maybe nothing we can do about it because it is an OOM?

There seems to be some accessibility signatures in the stack:

Comment 1

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

Tracking for 64 since the crash rate seems quite high.

Comment 2

[Eitan Isaacson [:eeejay]]

This was fixed in 65 in bug 1501496, and a followup bug 1505515.

From my understanding they will be approved and uplifted.

I'm worried because this might be indicative of a memory leak, but at least for 64 those patches should remedy it.

Comment 3

[Marcia Knous [:marcia]]

On 65 nightly, there were single crashes on the 20, 21 and 23rd builds after the patches landed, but since that build no further crashes. On 64b12, we have 4 crashes so far. We can keep an eye out and see how volume continues in beta.

Comment 4

[Julien Cristau [:jcristau]]

Looks like volume dropped from 64.0b11 to 64.0b12 and remains low in 64.0b13.  Enough to call this fixed?

Comment 5

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

Not high volume on release/beta, but probably also for the geckoview team.

Comment 6

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

Low volume crash, marking fix-optional to remove this from regression triage. 
Happy to still take a patch in nightly.

Comment 7

[Chris Peterson [:cpeterson]]

There have only been 15 reports from Fennec 65 and 4 from Fennec 66.0a1. I don't think we need to track this for GV.
