This is a bad one. Somehow you have stretched \TEX\ beyond its
limits. The thing that overflowed is indicated in brackets; it might be any of
the following:

$$\vjust{\halign{\tt#\hfill⊗\quad#\hfill\cr
alignsize⊗the number of simultaneous alignments;\cr
fmemsize⊗the number of words of auxiliary font information;\cr
hashsize⊗the number of different multiletter control sequences;\cr
idlevs⊗logarithm of the number of levels of grouping;\cr
memsize⊗memory used to store tokens and many other types of things;\cr
nestsize⊗number of simultaneous partially-complete lists;\cr
parsize⊗number of simultaneous partially-scanned arguments;\cr
savesize⊗number of values to restore at end of group or formula;\cr
stacksize⊗number of simultaneous levels of input;\cr
stringsize⊗number of independent operations on typesetting device;\cr
varsize⊗memory used to store boxes and many other types of things.\cr}}$$
If your job is error-free, the remedy is to recompile the \TEX\ system, increasing
what overflowed. However, there's probably something you can do to your job

that will make it run. Maybe you have specified an infinite macro-expansion;
then it would cause overflow no matter how big you make \TEX. If {\tt savesize} has
$\TEX$ has variable glue, as we discussed in Chapter 12, so spaces in \TEX's
math formulas actually can get a little thicker or thinner when a line is being
stretched or squeezed. Here is a precise chart telling about all the different
kinds of spaces that you can specify in math formulas:

There's no need.\par
