EXC_Resource - exceeded mem limit

With the latest updates from Catalina, and even on BigSur 11.0.1 20B29 with the latest OpenCore 0.6.4 commit seems like booting both systems causes a delay of 10+ seconds on this line:

This issue is persistent across reboots, I can provide logs if required.

remove the voodooinput from voodooi2c and keep voodooinput in voodoops2

This has nothing to do with my issue. And also, I don't have an I2C trackpad.

Well, this is not an OC problem, but rather something with macOS itself.

@vit9696 executing this command from macOS recovery removes the hang, any idea why?

csrutil enable --without kext

[vit9696]

Well, if you believe it is a regression, tell me the commit it happened in. Do you have enough RAM? Anything below 8 GB may be problematic.

Same problem using OC 0.6.3 after enabling igpu in bios for hw acceleration.
Haswell cpu ....nvidia card ...16GB ram ...gigabyte z97

Interestingly, macOS Catalina 19H2 doesn't have this hang. (With fixed OC version, stable, 0.6.3 - the testing conditions are the same as before)

I've even tried the latest BigSur (release, 20B50 on a clean install with an external SSD) + OpenCore and Kexts 0.6.4 (latest builds from dortania) but the hang of about 10 seconds persists.

What could MRT[74] mean?

What could MRT[74] mean?

'MRT' is just MacOS's Malware Removal Tool, and 74 is the PID of that running MRT process.
Whenever you install or update software, MacOS (XProtect I think) is simply supposed to briefly run and confirm it's not malware. But in some scenarios, MRT gets launched, hangs the CPU and overheats and only gives this warning; this has been happening at least as far back as 10.14.x. I get this too with different root-cause, on different software, and different version of MacOS.

See e.g. AskDifferent: MRT Process using large unbounded amount of memory
