Here's a bit of lore that has helped me track down similar problems. Termination issues tend to cause trouble at the other end of the bus from where the fault is. If the "far" devices are where the flakiness is showing up, focus on the "near" terminator.

In this case, the built-in 2CAN resistor might not be the right value for your heavily loaded bus.
