It is evident from the web browser console that the issue is with Apple, but it is concerning that it has not been fixed for such a long time. The stability and performance are worrisome.

I've been having trouble uploading images to the Apple Store for a long time, it's unbelievable.

All apps may crash using above steps.

Ignoring the SIGPIPE signal seems to lead the app to meet the app killed by the watchdog. signal(SIGPIPE, SIG_IGN);

@eskimo Could you please take a look at this issue? Thanks.

We also need this feature, expect apple can support it.

The main thread is waiting for the _pthread_list_lock that is held by thread 82. And Thread 82 seems paused by the JavaScript scavenger thread 2, thread 2 also called pthread_mach_thread_np. In this situation, the _pthread_list_lock will not unlock. The app will be force killed by the watchdog. By the way, thread 82 is created by the gcd queue. If we do not use the gcd queue will avoid the issue. Does apple notice the serious bug? Some implementation changes on iOS15.4 may lead to the issue, such as the JavaScript scavenger? Hope apple fix the system issue quickly.

Please post a full crash report for this. Recently we have taken a lot of time to analyze the issue of our app. But this issue only happens on iOS15.4. With the upgrade of iOS15.4, we're getting more and more crashes reports. We both think it should be a serious system bug. Refer to the full crash report in the attachment ('...' means I removed some stack of our image). Does anyone else has met the same issue? full_crash.log

I upgraded macOS to 11.3 and installed Xcode13 beta version, and resign the enterprise app, it seems to works.

I notice this change https://developer.apple.com/documentation/xcode/using-the-latest-code-signature-format My app code sign version is CodeDirectory v=20400

We also met the bug when the app builds with Xcode12 on iOS14. Hope Apple can fix the serious bug.
