Hi!

We have found a lib system_kernel.dylib (os_channel_flow_admissible) crash since iOS11 and later.

This bug is not highly reproducible but affects a large group of our users. You can find a stack trace below:

Is it a known issue? How can we fix it?

Thanks!

If you post a full Apple crash report for this crash I can take a proper look.

I’m sorry but that’s not a full crash report, it’s just a bunch of backtraces. I need the full report.

ps You can find an example of a full crash report linked to from this thread.

[hello_world sent me a crash report via email but it got lost in my inbox and thus I never got around to following up. Sorry!]

This crash report looks like something we’ve seen before (r. 36983155). It seems to affect a wide variety of apps, implying that it’s an OS bug rather than an app-specific bug. As far as I can tell it’s not showing up in iOS 12 beta, which makes some degree of sense because, with the introduction of the Network framework, this part of the OS has had a lot of work in that system.

So, my advice right now is to look out for similar crashes in iOS 12 beta. If you seen none, that’s expected and we can all move on. However, if you do see a similar crash in iOS 12 beta let us know (file a new bug report, but also post a follow-up here).

Share and Enjoy

I am using intel macbook 2017. I purchased logic pro x in 2018 jan or so and have never found any bug like this. BUT FOR THE FIRST TIME, in new MAC OS 12.2.1 Montery, which i updated last night, Logic pro Unexpectedly quits and never reopenes!!

Here is the crash report which is very similiar to the above mentioned libsystem_pthread.dylib . It seems apple's DYNAMIC LIBRARIES CRASH not only in iOS but also in MAC OS.

Logic Pro 10.7.2 unexpectedly quit in Mac Montery

This crash is definitely unrelated to the crashes discussed above. Those crashes were all related to a bug in the Network framework whereas this crash report indicates that the crash happened within Logic Pro itself:

Thread 0 Crashed::  Dispatch queue: com.apple.main-thread
0   Logic Pro X   …   DoMidiPlugAndPlay(TPnPMode, CmdFuncMode) + 568

Are you developing for Logic Pro? Or just trying to use it? I suspect it’s the latter, in which case I recommend that you escalate this via Apple Support.

kashifjawad, This is unlikely to be related to the crash that’s the subject of this thread. Please start a new thread with the details of your crash. Tag it with Debugging so that I see it. Also, please include the full crash report, per the instructions in Posting a Crash Report.

Everyone else, I’ve locked this thread because I don’t want it to become a super mega thread for every crash ever:

  • If you have a crash that’s not related to the original crash in this thread, please follow the advice I gave to kashifjawad above.

  • If you have a crash that’s directly related to the original crash, please start a new thread, reference this thread, and also add the Network tag.

Thanks for understanding!

Share and Enjoy
