Unclear that we can do anything about this, or should (so far only 7k users).

Also small crash rate with RtlFailFast2 https://crash-stats.mozilla.org/report/index/5953f534-4df4-433f-a7c4-6b0a10250110, and perhaps a few others.

All crashes are 32-bit.

So far we are not seeing crashes for 128.6.0esr.

With many instances of uptime < 1 minute, some of those users may need to download and install to get out of the crash cycle.

But there is hope because over 30,000 instances crashed just in the first day, but in the last 5 days the number of instances is only 20,000

[Wayne Mery (:wsmwk)]

crash rate as doubled, so ~70,000 users reporting crashes. The average is two crashes per user.

Comment 5

[Wayne Mery (:wsmwk)]

The crashes are nearly gone after January 21. BitDefender must have shipped a fix.

But there was an odd jump on a single day, Feb 12, for two of the signatures:

• 1,500+ for https://crash-stats.mozilla.org/signature/?signature=atcuf32.dll%20%7C%20mozilla%3A%3Aipc%3A%3AMessagePumpForNonMainThreads%3A%3ARun&date=%3E%3D2024-11-20T13%3A16%3A00.000Z&date=%3C2025-02-20T13%3A16%3A00.000Z#graphs
• 300 for https://crash-stats.mozilla.org/signature/?signature=atcuf32.dll%20%7C%20bdhkm32.dll%20%7C%20winapi%3A%3Aum%3A%3Abits%3A%3AIBackgroundCopyManager%3A%3AGetJob&date=%3E%3D2024-11-20T13%3A15%3A00.000Z&date=%3C2025-02-20T13%3A15%3A00.000Z#graphs

All version 32bit 128.5.2esr - which is expected.
About 500 user installations, averaging 5 crashes per user.

Also of note:

• No Windows 7 crashes (makes sense, version 128 and relevant betas do not support Windows 7)
• Beta channel crashes drop to near zero after 134.0b4

Crashes have continued with 128.6.0, 128.7.0, 128.7.1. But so far none for 128.8.0
