We will see....

There should be no difference in terms of which ESC can run however many poles. Sure, firmware has a part in it, but the ESC is still limited to firing the phases only so fast (whether it be firmware or hardware related, that limitation is still present). The more poles you have, the more phases that are in the motor, so the mork work the ESC really does have to do to create one revolution.
Mega also suggests keeping their motors under about 50,000 RPM on their motor selection tables. I'm willing to take a shot and say that this is due to their higher pole counts, and relates back to what What's Nitro was saying. That's also probably why they run just fine on a mamba ESC (the RPM that the motor spins is significantly lower than the problem setup mentioned by the OP).
I'm inclined to agree with him 100% that the number of poles coupled with the voltage it is being run on (a 6 pole motor being run at around 60,000 RPM is going to stress out the ESC, and the gearing is some nasty icing on the cake) is certainly contributing to the problem.
