This signature is spiking in Nightly 97 since yesterday (buildid 20211214094205).

Comment 2

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

New crash spikes align with the landing and relanding of bug 1712837.

Comment 3

[BugBot [:suhaib / :marco/ :calixte]]

Since the status are different for nightly and release, what's the status for beta?
For more information, please visit auto_nag documentation.

Comment 4

[Cosmin Sabou [:CosminS]]

The regressor has been backed out from mozilla-central and new nightlies have been requested. https://bugzilla.mozilla.org/show_bug.cgi?id=1712837#c18

Comment 5

[Ryan VanderMeulen [:RyanVM]]

This specific instance only affects 97.

Comment 6

[Ryan VanderMeulen [:RyanVM]]

Looks like bug 1712837 successfully re-landed without this spiking.
