I got this yesterday. I was running somebody elses code and I decided to see if it would run any faster using the "2 Donkey" method:
PHY UPDATE 1
PHY UPDATE 0
SYNC
Firstly, it crashed immediately with this message. So then I changed it...
PHY UPDATE 1
SYNC
PHY UPDATE 0
This time, it ran for a few seconds, but as soon as it came to an intensive part of the code, it crashed and died with the same error.
I imagine the important part of this is that I have a single core processor, and no PPU. My guess is that the physics calculations cannot be carried out fast enough, and the main thread assumes that whenever it gets called, the second thread
will be complete
