Arris SB8200 Comcast issues with "Dynamic Range Window violation"

I bought an Arris 8200 to resolve the dreaded Puma6 issues I was clearly having, and so far I have to say those latency issues are not happening (I've only had the modem for a day now though so far). But I do have a few concerns, is anyone else having these problems? - I am receiving these warnings in the event log, and they are occuring every _minute_ Warning(5) "Dynamic Range Window violation" - When accessing the status page at http://192.168.100.1/cmeventlog.html, it takes at least 30 seconds to load. Wondering if said logging above every minute might be exhausting memory. - I believe the event log is due to the channel 159 being out of range of the other channels, what is this channel used for? I couldn't find anything on the web.
