It is my theory from reading the investigations to date on this list and from personal experience, whenever the module does a hard crash (eg as above, memory corruption from a buffer overrun causes the CPU to crash) then the module has the potential of causing a number of errors on the CAN bus.
 
Rather than the crash, it could be the subsequent boot that causes the problem.
 
Previously I've caused the 2016 car to throw dashboard errors by typing "module reset" over SSH while charging was in progress. I assume this is an orderly shutdown, and hence it's the boot process that disturbs the CAN bus of an active car.
