1476346 - GeckoView onCrash is being called very often

Status: RESOLVED WORKSFORME

(GeckoView :: General, defect, P1)

Description

[Emily Kager [:ekager]]

With our Nightly users, we've seen GV onCrash be called very often. In fact it's currently our top Sentry event for Focus with over 7900 crashes from 882 users.

Should we be concerned with content crashes happening this often with such a small test group?

Do crashes that trigger onCrash() show up on crash-stats.mozilla.com and can we correlate them somehow?

These 7000+ onCrash reports might have been the 7000+ mozilla::gl::GLContext::InitWithPrefixImpl crashes from bug 1468747, though that crash was fixed in GV 62 beta about two weeks ago.

Chris is going to gather some more info.

I think those 7000+ crashes are GLContext::InitWithPrefixImpl bug 1468747, fixed in GV 62.0b3. Sentry reports that we are now receiving about 200-600 crashes per day [1] in GeckoView code, which is in line to the number of GeckoView crash reports we receive in Socorro [2]. I don't think any action is required for this bug, other than fixing the individual crashes
