Hello,
Since the first iOS 15 beta and even with all the next public releases, we have a very weird crash each time our app enters background.
The crash logs don't help at all unfortunately
Each time we see:
Exception Type: EXC_CRASH (SIGKILL)
Exception Codes: 0x0000000000000000 , 0x0000000000000000
Exception Note: EXC_CORPSE_NOTIFY

7 UIKitCore 0x00000001837c4b8c UIApplicationMain + 2124 (UIApplication .m:5013 )
And sometimes we have:
Kernel Triage :
VM - Compressor failed a blocking pager_get
or
Kernel Triage:
VM - pmap_enter failed with resource shortage
VM - Compressor failed a blocking pager_get
But no other info.
We can't reproduce it on simulators or on real devices with non-production release (linked to Xcode).
But the crashes are here each time we build a release version.
Any help would be appreciated!
NB: it seems similar to this one but we are not even sure

Many of you in this thread have opened bug reports in Feedback Assistant — thank you for filing those to help us address this! We have deployed a fix to the backend services that provide crashes for your app into the Xcode Organizer, so if you receive EXC_CRASH (SIGKILL) crash reports from now on through the Organizer, those reports should be attributed with an exception code to explain why the system terminated your app.
If you still see any reports without the exception code, please post the complete crash report to this thread using the attachment feature so we can verify that the code is still missing.
