Seemingly unnecessary log entries

[danielfm]

First of all, thanks for opensourcing this!

I'm noticing lots of identical lines in the logs, maybe there's something that can be done to make the logs less redundant.

For instance:

Are all these lines really necessary? Or are these an indication of some other issue?
