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
Triggered by Thread: 0

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
