Hello. I have two crash reports that are likely related, with the following kernel triage:

crash report 1: VM - (arg = 0x3) mach_vm_allocate_kernel failed within call to vm_map_enter
crash report 2: VM - Compressor failed a blocking pager_get

Both reports seem to indicate that the crash may be happening during (and perhaps caused by) the call to RubyLocalDB.saveStoreMetadata.

I have attached the reports below. I would really appreciate any insight into what the kernel triages indicate based on the stack traces. Thank you.

My experience is that the Kernel Triage section is a net that catches a lot of red herrings. And, indeed, that’s the case here. Consider this:

Exception Type:  EXC_CRASH (SIGKILL)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Termination Reason: RUNNINGBOARD 0xdead10cc

That 0xdead10cc code is important. See Understanding the exception types in a crash report for the details.
