Reading my logs makes me nervous

This sounds ridiculous, I know, but I get error messages in my logs and I don't know what they mean:

Also this -

Should I be worried about these or should I stop reading the console logs?

Why are you reading them?

 

[bingefeller]

To try and find out why my volume header thing happened. I then discovered all of these other "errors". I'm assuming all these things are normal?
