Occasional overfull \vbox warnings

Depending on the value of \aeheight I may or may not get Overfull \vbox errors. I don't understand why.

\documentclass{article}
\usepackage[margin=0.5in,landscape]{geometry}
\usepackage{multicol}
\setlength{\columnseprule}{0.4pt}
\setlength{\columnsep}{0.25in}
\pagestyle{empty}
\newlength{\aeheight}
\setlength{\aeheight}{6in}
\setlength{\parindent}{0pt}
\usepackage{lipsum}
\begin{document}

\begin{minipage}[t][\aeheight]{10in}
\begin{multicols}{4}
  \lipsum[1-2]
  \rule{4pt}{\aeheight}
\end{multicols}
\end{minipage}

\end{document}

However, if I set \aeheight to 3in, then I don't get such errors.

Can anyone explain why different values are generating the warnings?

The rule is too big when multicol does the balancing. – egreg Jul 11 '13 at 20:35
@egreg But then why doesn't it complain when the rule is 3in? – A.Ellett Jul 11 '13 at 20:39
Probably because it finds a good height before starting the trial typesetting. You can see the computations by issuing \setcounter{tracingmulticols}{2} – egreg Jul 11 '13 at 20:43
