;; The general idea is, that there is one process and process buffer
;; associated with each master file, and one process and process buffer
;; for running TeX on a region. Thus, if you have N master files, you
;; can run N + 1 processes simultaneously.
;;
;; Some user commands operates on ``the'' process. The following
;; algorithm determine what ``the'' process is.
;;
;; IF last process started was on a region
;; THEN ``the'' process is the region process
;; ELSE ``the'' process is the master file (of the current buffer) process

it cuts off pages. This error occurs when LaTeX finds too many figure
and/or table environments before it is time to cut off a page, a
problem that is solved by moving some of the environments farther
towards the end of the input file. The error can also be caused by a
``logjam''---a figure or table that cannot be printed causing others
to pile up behind it, since LaTeX will not print figures or tables out
of order. The jam can be started by a figure or table that either is
too large to fit on a page or won't fit where its optional placement
argument says it must go. This is likely to happen if the argument

("TeX capacity exceeded, sorry .*" .
"TeX has just run out of space and aborted its execution. Before you
panic, remember that the least likely cause of this error is TeX not
having the capacity to process your document. It was probably an
error in your input file that caused TeX to run out of room. The
following discussion explains how to decide whether you've really
exceeded TeX's capacity and, if so, what to do. If the problem is an
error in the input, you may have to use the divide and conquer method
described previously to locate it. LaTeX seldom runs out of space on a
short input file, so if running it on the last few pages before the
error indicator's position still produces the error, then there's
almost certainly something wrong in the input file.
The end of the error indicator tells what kind of space TeX ran out
of. The more common ones are listed below, with an explanation of
their probable causes.
buffer size
===========
Can be caused by too long a piece of text as the argument
of a sectioning, \\caption, \\addcontentsline, or \\addtocontents
command. This error will probably occur when the \\end{document} is
being processed, but it could happen when a \\tableofcontents,
\\listoffigures, or \\listoftables command is executed. To solve this
problem, use a shorter optional argument. Even if you're producing a
table of contents or a list of figures or tables, such a long entry
won't help the reader.
exception dictionary
====================
You have used \\hyphenation commands to give TeX
more hyphenation information than it has room for. Remove some of the
less frequently used words from the \\hyphenation commands and insert
\\- commands instead.
hash size
=========
Your input file defines too many command names and/or uses
too many cross-ref- erencing labels.
input stack size
================
This is probably caused by an error in a command
definition. For example, the following command makes a circular
definition, defining \\gnu in terms of itself:
\\newcommand{\\gnu}{a \\gnu} % This is wrong!
When TeX encounters this \\gnu command, it will keep chasing its tail
trying to figure out what \\gnu should produce, and eventually run out
of ``input stack''.
main memory size
================
This is one kind of space that TeX can run out of when processing a
short file. There are three ways you can run TeX out of main memory
space: (1) defining a lot of very long, complicated commands, (2)
making an index or glossary and having too many \\index or \\glossary
commands on a single page, and (3) creating so complicated a page of
output that TeX can't hold all the information needed to generate it.
The solution to the first two problems is obvious: define fewer
commands or use fewer \\index and \\glossary commands. The third problem
is nastier. It can be caused by large tabbing, tabular, array, and
picture environments. TeX's space may also be filled up with figures
and tables waiting for a place to go. To find out if you've really
exceeded TeX's capacity in this way, put a \\clearpage command in your
input file right before the place where TeX ran out of room and try
running it again. If it doesn't run out of room with the \\clearpage
command there, then you did exceed TeX's capacity. If it still runs
out of room, then there's probably an error in your file. If TeX is
really out of room, you must give it some help. Remember that TeX
processes a complete paragraph before deciding whether to cut the
page. Inserting a \\newpage command in the middle of the paragraph,
where TeX should break the page, may save the day by letting TeX write
the current page before processing the rest of the paragraph. (A
\\pagebreak command won't help.) If the problem is caused by
accumulated figures and tables, you can try to prevent them from
accumulating---either by moving them further towards the end of the
document or by trying to get them to come out sooner. If you are
still writing the document, simply add a \\clearpage command and forget
about the problem until you're ready to produce the final version.
Changes to the input file are likely to make the problem go away.
pool size
=========
You probably used too many cross-ref-erencing \\labels and/or defined
too many new command names. More precisely, the labels and command
names that you define have too many characters, so this problem can be
solved by using shorter names. However, the error can also be caused
by omitting the right brace that ends the argument of either a counter
command such as \\setcounter, or a \\newenvironment or \\newtheorem
command.
save size
=========
This occurs when commands, environments, and the scopes of
declarations are nested too deeply---for example, by having the
argument of a \\multiput command contain a picture environment that in
turn has a \\footnotesize declaration whose scope contains a \\multiput
command containing a ....")
("Text line contains an invalid character." .
"The input contains some strange character that it shouldn't. A mistake
when creating the file probably caused your text editor to insert this
character. Exactly what could have happened depends upon what text
editor you used. If examining the input file doesn't reveal the
offending character, consult the Local Guide for suggestions.")
("Undefined control sequence." .
"TeX encountered an unknown command name. You probably misspelled the
name. If this message occurs when a LaTeX command is being processed,
the command is probably in the wrong place---for example, the error
can be produced by an \\item command that's not inside a list-making
environment. The error can also be caused by a missing \\documentclass
command.")
("Use of [^ ]* doesn't match its definition." .
"It's probably one of the picture-drawing commands, and you have used
the wrong syntax for specifying an argument. If it's \\@array that
doesn't match its definition, then there is something wrong in an
@-expression in the argument of an array or tabular
environment---perhaps a fragile command that is not \\protect'ed.")
("You can't use `macro parameter character \\#' in [^ ]* mode." .
"The special character # has appeared in ordinary text. You probably
meant to type \\#.")
("Overfull \\\\hbox .*" .
"Because it couldn't find a good place for a line break, TeX put more
on this line than it should.")
("Overfull \\\\vbox .*" .
"Because it couldn't find a good place for a page break, TeX put more
on the page than it should. ")
("Underfull \\\\hbox .*" .

probably caused by a problem with a \\\\ or \\newline command---for
example, two \\\\ commands in succession. This warning can also be
caused by using the sloppypar environment or \\sloppy declaration, or
by inserting a \\linebreak command.")
