404s logged in error.log?

[akurilin]

I was wondering if someone could confirm that requests resulting in a 404
response are by default logged to error.log at error level "error".

Is that normal, or is there some piece of configuration I am missing that
will stop them from being logged to error.log? I figured 404s would be an
un-exceptional event that doesn't require error logging, but perhaps I'm
simply not handling that situation correctly in my configuration. Worth
double-checking.

Thank you!
