Dear Joseph,

I use Siunitx within beamer and meet the following errors:

! LaTeX Error: Too many math alphabets used in version normal.

I've tried to strip down my code to obtain a minimal example but
failed. Any hints on this issue or give me some hints on preparing
the minimal example?

Hello Hongyi,

There was an issue with an earlier version of siunitx in this area.
Which version of the package are you using? Can you let me have a copy
of your preamble: I probably know what to look for!

I've sent it to your mail by private. Thanks a lot.

Cutting things down, I got to:

\documentclass{beamer}
\usepackage{siunitx,bm,pxfonts}
\begin{document}
\end{document}

a giving a problem. A little more work reveals that you don't have to
load siunitx to see the problem:

\documentclass{beamer}
\usepackage{bm,pxfonts}
\begin{document}
$\mathsf a$ $\mathtt b$
\end{document}

The issue occurs because siunitx needs to check on the current \mathsf
and \mathtt fonts at the start of the document. This is done by
setting a couple of boxes and getting the font information. As you
can see, this fails with a combination of bm, pxfonts and beamer:
between them they use up all of slots available.

There is not really much I can do about this: perhaps report it to the
beamer maintainers (if you load bm and pxfonts then beamer should
presumably keep out of the way).

I've reported it to the author of beamer: Prof. Dr. Till Tantau
<tan...@tcs.uni-luebeck.de>.

Thanks again.

the bm documentation has information on saving math alphabets -- read
it.

(math alphabets are a ridiculously limited resource.)

You are telling me. This has caused me a lot of headaches in siunitx!
