在我的自定义定理和证明环境中使用 mdframed 框时，我收到很多“Overfull \vbox”错误。我已将问题简化为下面的最小示例。我使用方程式来下推环境，以便它们可以拆分到两个页面。
问题是什么？我该如何解决这些过满的 \vbox 警告？

不要使用mdframed：它已被废弃，因为与此同时tcolorbox出现了更强大的软件包。
\documentclass[a4paper, 12pt]{article}
\usepackage[many]{tcolorbox}
\usepackage{amsthm}
\usepackage{amsmath}
\newtheorem{theorem}[equation]{Theorem}
\NewEnvironmentCopy{fproof}{proof}
\tcolorboxenvironment{theorem}{sharp corners,colback=white,boxrule=0.4pt}
\tcolorboxenvironment{fproof}{}
\begin{document}
\begin{equation}
\begin{aligned}
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2.
\end{aligned}
\end{equation}
\begin{theorem}
A theorem.
\end{theorem}
\begin{fproof}
We see that
\begin{equation}
\begin{aligned}
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2 \\
E & = mc^2.
\end{aligned}
\end{equation}
so we finished our proof.
\end{fproof}
