How often is this a fatal error, i.e. the document is OK and there
really isn't enough capacity, and how often is it the result of an error
in the document?

I have not encountered that on Linux/Mac (ie more than 25 years) unless there
was a LaTeX syntax issue.

I only encountered this way back olden days, generally gnormous documents on
machines with "tiny" amounts of memory with LaTeX systems built with small
limits to conserve memory. Or else with documents that had things like
runaway recursion problems, etc. I believe current versions of LaTeX builds
are fairly generous with the various fixed allocated elements. These fixed
allocated elements are controlled in config files and relate to how the format
files were built -- it is possible to custom build the format files with
larger capacity, if you really need to.

It turned out to be a syntax issue. Interestingly, the document both
compiled and produced the desired output up until the error. Probably
runaway recursion. I managed to fix it.

IMNSHO, almost never.

Almost always, in my case.

Hard to answer. I got the error just three days ago due to there really
not being enough capacity. Probably most of the time, though, it's due
to an error in the document, such as an infinite loop.

P.S. In case you're interested, the lack of capacity was due to a very
complicated TikZ graphic. See
https://github.com/samcarter/TikZbricks/pull/3 for what I was trying to
draw. In my case, LuaLaTeX was already configured with enough capacity
to handle the document even though pdfLaTeX threw a "! TeX capacity
exceeded" error.

Fascinating edge case.

I would of course just includegraphics it but if one is bored :-)-O

This type of error gives reason to check the (closing) braces. In the
earlier days I had to adjust tex.conf but that has been maybe 10 years
earlier.
With the use of something like texstudio that error has not happened for
some time.

Kind regards.

When I demand some hard calculation to TeX (i.e multiplicate two
operands with 10000 digits)
I've got this fatal error a 25th december a long time ago when I want
to post a card in fr.comp.text.tex with a Chrismas tree in PostScript
with *many* flashing stars and flashing tinsels... very cute :-)
