After iOS 15 release, we seeing a lot NO_CRASH_STACK crashes from Xcode organizer with so many different crash stack.
But look into the crash logs, we find some regular pattern:
-
Most happens on old devices like iPhone 8.x or iPhone 9.x.
-
Most of them happened in 10 seconds after launch.
-
There is no crash reason in log.
-
All crash code is 0x00.
-
Most of them have "Kernel Triage: VM - Fault hit memory shortage" or "Kernel Triage: VM - Compressor failed a blocking pager_get".
So I have no idea how to solve it because it looks like our app killed by system with some reason that not shown in log. I guess maybe is memory issue but I have no idea how to locate the problem logic or function in our code.
I also posted a report: FB9816327
Does anyone get some issue?
Is there any idea how I can locate the issue and fix these crashes?
Here are some of the crash logs:
