Cable modem event log

My cable modem keeps logging this event quite frequently, sometimes every hour, and sometimes every 15 minutes.  It alternates between:

US profile assignment change. US Chan ID: 8; Previous Profile: 10 13; New Profile: 9 13.
US profile assignment change. US Chan ID: 8; Previous Profile: 9 13; New Profile: 10 13.

Whenever the cable modem logs this, it seems to coincide with some packet loss.  Connection looks good as far as I can tell and within spec. I tried restarting the cable modem. Same result. Just wanted to check and see if this is a common issue for a cable modem to continue switching the upstream profile, or if I need to have Cox investigate further:

Thanks!

    Could be congestion(to many people online on your node) or a signal issue with the upstream. Probably a issue with the OFDMA channel. Can you post your signal levels? Also, when did the problem start and what changed around then? Was it around the time your upload speed increased?

      I upgraded to a 1 Gig connection late last year. Never looked at the logs until a few days ago.

        I only see ATDMA(QAM). Do you see any data for OFDMA? Also, your downstream levels look high. They should be +10 to -10dB. Are you going through a coax amplifier? If so, I wonder if that is causing the problem.
