I've reached out to Motorola as the number is climbing at > 200 million errors a day. (I wonder if there is an overflow error at 1 billion?) The initial answer is "The OFDM channels are different from the rest. If every other channel is zero, except the OFDM channel, then you need not worry about that channel." I responded to the effect that I am aware the OFDM channel is different, but would still like a root cause or at least a meaningful explanation.
Sounds like a firmware issue but one that doesn't effect connectivity. Like you said
Modem is stable, everything is working wonderfully.
Don't worry about it.
I did get an additional update today, which expressed concern at the power levels being high. That's something Cox would have to address and is certainly more trouble than it's worth given the overall performance.
