I think Bug 1405290 is related to the bugs generating crash signatures of [@ IPCError-browser | ShutDownKill ] with processor notes "Signature replaced with an IPC Channel Error, was ______.". 

I had the following crash reports generated while updating Firefox Nightly. 

Therefore, Bug 1405290 blocks Bug 1279293(IPCError_ShutDownKill) 
(Or could be changed to "See Also".)

And Bug 1405290 is See Also Bug 1424451.

2017-12-10 2138pm Firefox Nightly crashed while updating.

IPCError-browser | ShutDownKill seems very high in nightly. Jim - can you help us triage this particular crash signature?

I don't see shutdownhang in the top crash signature list any more (well, I see a few), which was always our top crash. I think whatever we were doing that processed the signatures to be things like "shutdownhang | foo | bar" broke. Will, could you take a look into this when you get back from holiday? Thanks.

Comment 9

[Andrew McCreight [:mccr8]]

I'll file a separate bug.

Comment 10

[Andrew McCreight [:mccr8]]

Ah, I guess this has just been the top crash for a while, looking back at old builds. I just got confused about it. Sorry.

Comment 11

[Trevor Skywalker]

I don't think the processor for shutdownhang signature is broken. There are still many signatures containing "shutdownhang". 

https://crash-stats.mozilla.com/search/?signature=shutdownhang&product=Firefox&date=%3E%3D2017-12-15T23%3A12%3A47.000Z&date=%3C2017-12-22T23%3A12%3A47.000Z&_sort=-date&_facets=signature&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#facet-signature	

Shows 50 signatures containing the term "shutdownhang" accounting for 186,115 Crash Reports over the past 7 days.

---

Shutdownhang crashes are still top crashers though. 

Do they have a [meta] bug to help with organization? 
(Should they have a [meta] bug?)

Looking at Top Crashers for Firefox 57.0.2
Top 300 Crashing Signatures. 7 days ago

https://crash-stats.mozilla.com/topcrashers/?product=Firefox&version=57.0.2&_facets_size=300

Find (Ctrl+F) "shutdownhang" shows 112 matches out of 300 results. So about a third of all top crash signatures are related to "shutdownhang". 

Out of the top 30 there are 14 with "shutdownhang" (or about half).

This our generic "a process didn't shut down in a timely fashion so we killed it." signature.

[Worcester12345]

Should add "DUPEME" key word.

Comment 15

[Hani Yacoub, Desktop QA]

Closing this as resolved:worksforme since there were no crashes in the last 6 months for this signature.

Comment 16

[Andrew McCreight [:mccr8]]

This crash has happened recently.

Comment 17

[Jens Stutte [:jstutte]]

Since we landed bug 1727149, the signature IPCError-browser | ShutDownKill spiked up here.

But I was curious about the (rare) [@ core::ptr::drop_in_place<T> ] signature, as we seem to have difficulties to scan those stacks and opened one with Visual Studio:

Comment 18

[Jens Stutte [:jstutte]]

Adjusting some signatures. In particular, [@ IPCError-browser | ShutDownKill] is tracked well in bug 1279293, so let's concentrate here on the other, more special ones.

Comment 19

[Jens Stutte [:jstutte]]

[@ mozilla::widget::WinUtils::WaitForMessage | nsAppShell::ProcessNextNativeEvent ]
seems to happen only in parent processes and not in any shutdown context, apparently.

[@ core::ptr::drop_in_place<T> ]
has very few instances and again happens only in parent processes. All instances have just one frame on the main thread.

I cannot really see any relation to this bug's title anymore?

Comment 20

[Jens Stutte [:jstutte]]

FWIW I filed bug 1799742. The other signature had a bug already, it seems.

Comment 21

[Jens Stutte [:jstutte]]

Marking invalid as of today there is nothing left to do here.
