The profile is from an M1 Mac, I'm not sure if the same issue exists on other platforms.

Note: at the time I captured the profile, there was a content process suffering from bug 1755864.

Unfortunately, our team does not have the domain knowledge to fix this problem and does own this data, along with its collection/reporting code. Going as back as bug 829439, the relevant component seems to be Core::XPCOM.

In general, our team is responsible for the data collection tools (e.g. Legacy Telemetry, Glean SDKs) but not for the code using our tools to collect their data.

Component: Telemetry → XPCOM
Product: Toolkit → Core
See Also: → 1779138

Bug 1682508 shouldn't affect this. It didn't change the way we collect the telemetry, just the process we collect it from.
