Which Signal version are you on?

robwilkes commented 3 years ago

at the time it was 5.12.2, I have the debug log, is it safe to attach here?

ksaadDE commented 3 years ago

Are you sure it was Signal? If it's a Mac Book Air a few people have already reported that their macs got in trouble: https://www.reddit.com/r/MacOS/comments/p05ut5/m1_mac_random_crash/

Seems to be again such a case where Apple bugs their system xD

robwilkes commented 3 years ago

It could be, however the crash dump specifically points at the Signal Helper process which looks to be related to Signal Desktop.

The link you provided says the faulting task was ‘kernel_task’ not Signal Helper, but I guess it could be a generic issue and the task identified a symptom and not the cause, however it’s the only thing I have to go off of.

I'm not a Apple expert, but as far as I know Apple does a lot to protect their Kernel and so on (sandboxing, etc) So I guess the Signal App, including the Helper, wouldn't run in any task near the kernel. Therefore I would argue it's a top down problem, so the kernel itself has some issue and kills the signal helper and points at the Signal Helper.

Also I guess the Signal Helper is also written with electron, as far as I know, electron uses heavily safe code.

indutny-signal commented 3 years ago

@robwilkes sorry you ran into it. Few questions: did you have any additional crashes like this after initial report? Do you happen to see any crashes with other electron apps like Slack or Discord?

I honestly don't know if there's much we can do about it since Signal is just a user-land Electron app and although we have some C++/Rust code that we use - it shouldn't be able to crash your OS.

robwilkes commented 3 years ago

Hi @indutny-signal . Haven't experienced any other crashes in the 9 weeks prior, and the two weeks post, with Signal, Discord or VSCode..

Happy to accept it's an anomaly that maybe isn't related to Signal despite the crash report.

indutny-signal commented 3 years ago

Appreciate your prompt response. I'll tentatively close the issue, but feel free to post more info here or reopen it if you ever see a crash like that again. Hope it will run smoothly for you from now on, though!
