Package scrpage2 Warning: seems you are using a very small headheight.
(scrpage2) If you get overfull \vbox warnings at almost every
(scrpage2) page, you should increase headheight e.g. writing
(scrpage2) \setlength{\headheight}{1.1\baselineskip}
(scrpage2) into the preamble of your document.
(scrpage2) A better solution would be to use typearea package.
