shravanrn, is this an OOM?

Comment 2

[Gian-Carlo Pascutto [:gcp]]

Regardless crash volume suggests this isn't S2.

Comment 3

[Shravan Narayan]

Sorry for the delay in getting back. At first glance, yes. This would be an OOM. Unfortunately the crash report data seems to have gone away, and the only other crash I see is a low volume crash on an older ESR of Firefox (91) and is related to Lucet (which we moved away from in favor of wasm2c).

I'll mark this as "invalid" for now, but we can re-open if we see more of this
