Internal Error (IOAF code -536870211)

We have an application which generates occasionally this error on command buffer scheduled (and completion):


Internal Error (IOAF code -536870211)


This occurs when running on an iMac, Late 2012, with a NVIDIA GeForce GT 640M 512MB.


Would anyone know what this error code means?


Thanks,

I forgot also to mention that this is running on macOS Catalina (10.14.6).

Only times I've seen this kind of issue is when you try to execute kernels that take way too long, or when your kernel needs inputs/outputs that cannot all fit in VRAM at the same time.
