FWIW, there is a known glitch with some makes / models of modem's firmware where the measuring mechanism incorrectly reads the power level, the SNR, and the bit errors for that channel. So it reads many errors when there really aren't.
The bit errors are really pretty low on the QAM256 channels.
Are you actually experiencing any connectivity problems ? The downstream stats are good. Please also post the upstream power level figures.

It's good. Are there any error / event log entries ? If so, please post them as well.

Yeah. There is not a "category" only for upstream events. The logging feature logs all general RF errors / events.
The signal stats are o/k but the error log entries indicate that something is going on. Perhaps there is noise ingress into the line(s) somewhere.
There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.
I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They will be able to poll the CMTS to see whether or not everything is in the green zone, see your node / cable plant and modem health, and also see a history plot for the modem. You should get a reply here in your topic. Good luck !

Hi bdm1955, I'd be happy to check your signal levels to help pinpoint where this issue could be coming from so that we can get it resolved. To get started could you please send me a private message with your full name and account number by clicking on my name (ComcastAmir) and then click "Send a message"?
