 Giuseppe—

 I am not using either the amsl or the nath modules. Never had to
 before. (The file has compiled successfully in its current form, but
 that was about a week ago.)

 If I should be using one of these modules, which do you recommend?

Sorry, I wasn't suggesting you should use these modules :)
On the contrary, I just recently found a bug in them that gave an
error similar to the one you found, when using point sizes
over 12. Since I knew the fix for that I was hoping it was
your problem, but sadly it isn't.

 I inserted
 \usemodule[t-amsl]
 into the preamble and got the same error message:
  ! Math formula deleted: Insufficient symbol fonts.

 But, when I inserted
 \usemodule[t-nath]
 the error message was
  !TeX capacity exceeded, sorry [input stack size=5000]
 which seems much more promising.

 Assuming that increasing the input stack is possible and desirable,
 how do I do it?

Please disregardi this, and remove the two modules. Since it
seems the 'Missing symbol fonts' problem only happens with a
big document, try the usual 'divide and conquer method':
terminate your document right after the formula that gives
the error, and progressively comment out halves of the
preceding text until you manage to isolate the chunk of text
preceding the formula that generates the error.

Example: say that that from \starttext to \stoptext there
are 300 lines, and that the formula is at the last line.
Then you comment the first 150 lines and see if the error
occurs. If it doesn't happen, you uncomment the first 150
and comment the subsequent 150 (Except for the formula, of
course). This way you can tell which half causes the error.
In the uncommented half that causes the error you repeat the
process (75 lines at a time), then again and again until you
manage to focus around the shortest document that causes the
error.

Giuseppe—

Actually, it can happen with a very short document too:

\starttext
\grk{\overbar{\grk{kj}} Kull'hnhc d$^{\hbox{\tfx\grk{ou}}}$ med'eonta  
ka`i Arkad'ihc polum'hlou}


\stoptext

will produce the
! Math formula deleted: Insufficient symbol fonts error.

To generalize: all my attempts to enter mathmode when the bodyfont is  
Greek (using one of the fonts in Thomas Schmitz’ Greek module) fail  
because of insufficient symbol fonts.


I wonder if this bears of the fact that in this module the fonts have  
to be defined at every size used in the document. The relevant line  
in type-tasgreek is

\definebodyfont
[30pt,25pt,20pt,18pt,17.3pt,14.4pt,14pt,12pt,11pt,10.5pt,10.1pt,10pt, 
9pt,8pt,7pt,6pt,5pt,4pt]

[rm]

My environment file sets the body font size to 10.1 pt.
