Release Note Request (optional, but appreciated) [Why is this notable]: [Suggested wording]: [Links (documentation, blog post, etc)]: Meta bug for ShutDownKills with e10s at Windows. We can expect that shutdown hangs are individual issues vs. a generic problem. (https://bugzilla.mozilla.org/show_bug.cgi?id=1116884#94) ShutDownKills have all in MCR, under "Metadata", "ipc_channel_error", "ShutDownKill" as the text.

We don't track metas. For any signature that is particularly high or interesting, file individual bugs.

Kevin, Margaret: This bug shows up alongside top crasher ranked #6 on FennecAndroid 44.0b2. The title is e10s specific so it is a bit confusing but there are so many signatures associated to this one. Perhaps we should split this up into two bugs: desktop-specific and Fennec-specific. Please let me know if I can help.

Please leave this bug to the e10s issue, we have enough hassle with those. Please file new bugs for signatures seen in non-e10s builds or products, even if they might match some signature on this bug.

I don't see a reason to track on this for e10s. According to a super search query - https://crash-stats.mozilla.com/search/?product=Firefox&ipc_channel_error=ShutDownKill&dom_ipc_enabled=!__null__&_facets=signature&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#crash-reports We have a total of 25 signatures across our entire install base, with e10s enabled in mc, aurora, and a small percentage of beta. Interesting though is that if I remove the ipc flag from the search, the numbers go higher. I don't understand how that's possible. https://crash-stats.mozilla.com/search/?product=Firefox&ipc_channel_error=ShutDownKill&_facets=signature&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#crash-reports http://mxr.mozilla.org/mozilla-central/source/dom/ipc/ContentParent.cpp#3644

Spoke with billm about this, turns out we use TabParent and TabChild in the background thumbnailing process as well. That's the source of a majority of these shutdown issues.

kbrosnan, you're better at crash-stats than I am. Can you help look into what's going on here?

This bug is intractable. I don't see how all the many signatures in the bug can be evaluated. Focusing on specific signatures would be the thing to do. Though without any context I don't know which ones are most common.

(In reply to Tobias B. Besemer [:BesTo] (QA) from comment #27) > Shutdown didn't worked; crashed with [@ crashme.dll@0x111a ]. > > Can somebody work with this data and analyze it ??? I don't think a crash in the crashme addon helps anyone too much.

If there is something for Fennec to track it should be in a separate bug.

So my understanding is that a ShutDownKill crash is a crash, initiated by code in TabParent.cpp as described in bug 1268711 comment 0, where the parent process tried to kill the child process and the child process did not terminate within the expected period of time. As I described in http://dbaron.org/log/20101111-crash-future , crash signatures are a heuristic we use for clustering related crashes into problems that are likely related to each other. This works for crashes because the signature is generally based on the exact code that was executing at the time the crash happened. But sometimes multiple unrelated bugs show up under the same signature; other times the same bug shows up across multiple different signatures. Ideally, we want to use bugzilla track bugs, and then fix those bugs. This means that we do *not* want a single bug report per signature, but instead a bug report per underlying fixable problem. We can often approximate these based on things like (a) steps to reproduce (b) common regression ranges or (c) other common characteristics, like extensions. For bugs like these where we're recording a crash report for a hang, the top of the stack may be much less relevant for clustering related crash. If the hang is because there's a deadlock, it is still relevant. However, if the hang is because we're running a bunch of code that is yet to finish, the signature will report the innermost code that happens to be executing at the moment of process termination, rather than the code (higher on the stack) that is responsible for the long-running algorithm. This means that for ShutDownKill crashes, signatures are generally not useful. Seeing a particular signature in a ShutDownKill crash doesn't mean that the named function had anything to do with the problem, whereas in an actual crash, seeing a signature means that something bad happened in the code in that function, even if the function wasn't at fault. I filed bug 1268711 to make the ShutDownKill signatures look different from other signatures, which should help with this problem. But until that happens, please be careful not to mix information about [@ signature] as a ShutDownKill crash and [@ signature] as an actual crash in the same bug report. This bug, as reported, is not actionable. Separate bug reports should be filed on the higher-level things that are hanging, i.e., the common code higher on the stack that is causing the child process to ignore the request to terminate. But these bug reports should not be mixed with bugs on other types of crashes, even if https://crash-stats.mozilla.org/ likes to suggest them to you.

Most of the crash signatures from 47b1 currently associated with this bug are not actually instances of this bug. There are a bunch of bugs with "(msgtype=0x7,name=???) Route error: message sent to unknown actor ID" which are being incorrectly associated with this bug. The actual frequency of ShutdownKill is very low. I'm going to remove all of the existing crash signatures which are in fact instances of the compositor shutdown race issue bug 1255823. To the extent that this really matters, let's modify the signature to record these specifically. I've filed bug 1219672 to modify all crashes with the ipc_message_error annotation, since the stack is unlikely to be the interesting classification mechanism for these. dbaron, if you see instances where the normal crash signature isn't a good classification tool, remember that we can change it pretty rapidly.

OK, normally the user open a shutdown-crash-sig in about:crashes and want to find there - or somewhere at https://crash-stats.mozilla.com/home/product/Firefox - some information about the crash he have every day... at least that this prob is known to Mozilla... So I/we should add there some open bugs that shows the user that the shutdown-sigs are known and someone working somewhere on it... If now the sigs get removed from this bug and it is not allowed to add any link to the other bugs, so the user have no link to any bug, or just to closed bugs that explain that this sig was fixed a long time before... How will Mozilla handle this problem now ???

Should I now really fill one bug for each shutdown-sig that appears every day, name it as a shutdown-bug that is not related to other bugs with that sig and then add a dependency to this bug ??? (I telling Mozilla since months/years about all the performance & stability problems on Windows... I know/see that I had a lot of impact with my feedback over that last years and it was getting much better again since I fight for it again... But really: I help here the Users and Mozilla to get a better image and market-share again !!! And it p*ss me really off that I have to do this in my spear-time, for no money and it is every time a fight with anyone at Mozilla !!! Should I really just give up and switch e.g. to Chrome as the most other freaks in the past too because this project seems to have lost the spirit of the beginning for years, maybe with the name-switch to Firefox ???) (And something more: If no one of Mozilla still don't know how much I have done for the Win-Users in the last years, then Mozilla have lost the overview of his own Main-Project completely and that maybe a long time ago !!!)

And if I telling the truth ATM: Seems the company lost the overview! The silicon valley have no clue what the "outside world" is doing and need! The company only works with Macs & Linux, don't get it, that ~90% of the world using Windows! Don't understand that the most parts of the world have computers with less performance, use them for more years and have a much slower internet! The employees don't really use the browser to do a lot of things in the web because they are busy with programming it... ...the tests are automated, the programmers program for the tests and no one really know why this tests don't cover the real problems of the users! FF supports now much more standards then every other browser, but is much worser to use for daily use then other browsers! Instead of finding solutions in communication with users, manufacturers and programmers of the pages the users use, the feedback is often that Mozilla have done all well and the problems are only the others... Mozilla is interested in getting e.g. extensions programmers to use the newest APIs, give a feedback, but the communication and the "lets do it together now to get it together running, now" is missing! Instead of delivering fast solutions for the users and programmers and improve them after that step-by-step, the users and programmers have to wait for months or years, because Mozilla won't ship a "not perfect solution" yet! Seems the project is run by the company - no more by the open source community and the foundation! Even long term volunteers need to fight to get listened, get excluded of the most information/decisions, get no good/helpful feedback e.g. in the forums and everything is absolutely controlled by the company! Sometimes the volunteers feel to be joked, because things get fixed in the background, giving no feedback to the community there and what was the problem; the employees do as the problem never existed! I don't know if this is (like it seems by other companies) a problem of the US-Business to don't show mistakes, try to give nobody a chance to go e.g. to the court or the press, is it "political correctness", arrogance, or what ever... but IMHO the most other parts of the world don't understand it! Speaking with people "strait forward" (IMHO) mostly brings faster and better results, even if the others are maybe p*ssed off in the first moment! But we are all humans! We have all feelings and it should e.g. in a "real community (driven project)" be allowed to show this feelings! Even from employees! And the problems seems to don't be single employees! Seems there is a real leak of management and a lost of overview !!! Sorry !!! My viewpoint and that straight forward!

Note many older bug reports will likely not be changed to using the new signature. Best not to link them to "Crash Signature" as it causes confusion.

Removing dependencies that are not actually about ShutDownKill crashes, including everything predating 1124933, which created them.

While not all old crash reports have been reprocessed, any new crashes have the [@ IPCError-browser | ShutDownKill ] signature, and adding other signatures to this bug will mislead people seeing actual crashes with those signatures by incorrectly leading them to this bug.

We're going to be seeing a spike of these reports thanks to our "submit your old crash reports" notification that just landed in the 6-2-2016 nightly (bug 1269998). Signatures here aren't usually crashes in code since these reports are generated when the chrome process content shutdown timer times out (5 seconds, based on 'dom.ipc.tabs.shutdownTimeoutSecs'). Here's a helpful proto signature crash list to find common stacks - https://crash-stats.mozilla.com/search/?product=Firefox&signature=%3DIPCError-browser%20%7C%20ShutDownKill&_facets=signature&_facets=proto_signature&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#facet-proto_signature

Something like 20% or more of the crashes in the 6-1 Nightly have the signature [@ IPCError-browser | ShutDownKill ], which seems really bad.

Track 51+ as the volume of crashes is high in 51.

Un-track 50/51/52 because this is meta and we've already tracked for bug 1279293.

Too late for firefox 52, mass-wontfix.

In my experience one of the cause of shutdownkills may be slow HDDs and not enough RAM. Here is my theory: 1. FF is running, alongside something else that does a lot of IO (could be anything, including Windows Update, random bloatware, malware scanner, whatever) 2. User closes the browser, FF starts shutting down all processes 3. The processes start shutting down, but need to do some IO and get bogged down due to HDD trashing, for many seconds. If there is not enough RAM, the pagefile will be hit many times and everything bogs down to glacial speeds. 4. Eventually the process shutdown times out, the processes are deemed hung (even though they are just blocked by IO), so they are killed.

Clogged, please look also at bug 1279293 comment 89.

Is it possible that you set the write-privileges (on HD) for FF in Windows higher? This creates write errors now in other programs running on the system! And [IPCError-browser | ShutDownKill] was down by <60k and is now up by >155k crashes! Look at: https://crash-stats.mozilla.com/signature/?product=Firefox&signature=IPCError-browser%20%7C%20ShutDownKill Now more uptime with FF for the users but also more crashes while shutdown?

This is what should really happens: FF is a really "big" program with a very big & complex code. Due to the architecture of Win-OSes and/or the "Microsoft Visual C++"-Compiler, there is no really good GC (Garbage Collection) for Windows/the Program. The programmers have to do it in the code of FF... Now, there are some complex pages that always reload content... Pages like Facebook, GMail, ... ...and/or there extensions for FF that are not multi-process-compatible and/or not based on the new WebExtension-Standard... This leads to a high memory use of FF over a long/the run time of FF... Now happens the steps "clogged" explained... ...but the "real" problem is the "not so good" GC and the amount of mem FF used over the run time! What you really should see if you have a shutdownkill-crash is, that FF try to make this GC/"the cleanup" of the process(es) at the end of its running... If you have a "older system" with less mem and/or slow HDs, this gets just more visible! You can see your virtual used mem (by the pagefile) in your task-mgr in Win... The crashes have (normally) nothing to do with the tasks (EXE-Files) FF starts at the end! They have only something to do with, when FF is not able to start them because of to much I/O on the system! So FF shouldn't use more priority for itself then other tasks or FF runs, but the system starts to fail in other tasks.

(In reply to Tobias B. Besemer [:BesTo] (QA) from comment #68) > Is it possible that you set the write-privileges (on HD) for FF in Windows > higher? > This creates write errors now in other programs running on the system! Is it possible that the rights for FF (some threads in the code) are still above normal in Windows? I still have those I/O-Errors since days/weeks...

This problem started appearing in FF 55 beta. I've had e10s with > 1 content processes for multiple versions now but only in 55 it started hanging on shutdown which prevents Windows from shutting down correctly.
