CM1000v2 modem CM-STATUS Messages. Large amount of errors on Downstream OFDM Channels

Hello, I see these errors in the event log and I am wondering what the cause and fix might be? I have made sure all connections are tight, replaced the one splitter in the system with a new splitter I got from comcast, however that did not seem to resolve the this issue.

The signal status values were o/k at that snapshot in time (SNR is a tad lower on channel #28). Are you actually experiencing any connectivity / performance problems or just focusing on those error log entries ?

@EG​ EG Thank you very much for your reply! Long story short yesterday I swapped out a SB6190 for the CM1000v2 noted above to see if the modem was the issue.

The SB6190 starting rebooting itself intermittently. It was about 1.7 years old. 

Everything seems to be working good now with the CM1000v2 but I wanted to make sure the CM-STATUS messages it was reporting were not issues.

Quite welcome ! They may or may not be a problem. If you are no longer having any connectivity problems, then don't sweat them. Live with the new modem a while and see if the re-booting issue returns. Please post back here with the outcome.
