Error in DSL Gateway System Log

[mcintoshbear]

I was looking at my DSL Gateway (Modem & Router) System Log and I saw the following entries. Is there anything to be concerned about?

All of that for the most part is noise. The line about failing to retrieve the new version seems like a software update which is unable to complete, or begin. That should correct itself once a new version of the modem firmware is available.
