TeX capacity exceeded, sorry [hash size=20000]

Question

I'm using a lot of packages right now:

\usepackage{mathtools}
\usepackage{amssymb}
\usepackage{array}
\usepackage{float}
\usepackage[colorlinks=true]{hyperref}
\usepackage[usenames,dvipsnames]{color}
\usepackage{verbatim}
\usepackage{tikz}
\usepackage{pgfplots}
\usepackage{chngcntr}
\usepackage{enumitem}
\usepackage{ctable}
%\usepackage{showframe}

\usetikzlibrary{plotmarks}
\usetikzlibrary{arrows}

%subfigures
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}

%inline lists
\usepackage{paralist}

So, this error started to appear when I started to \usepackage{pgfplots}. Changing the order changes the details of the error message (it chokes on loading a different library), Without removing any of the packages, how can I get this to work?

If you really absolutely need more capacity, you can ask a wizard to enlarge me.

Where can I find a wizard?

Answer 1

I have fixed it.

In the latex configuration file, I just increased hash_extra and then pool_size by a factor of 10:

hash_extra=100000
pool_size=5000000

If I'm not mistaken, these are in bytes, so 5 MB for a pool is very reasonable. If I encounter any more errors, I'll likely make pool_size 50MB.

For bakoma tex, the configuration file is called texmf.ini in the root install directory.
