# Again: ! TeX capacity exceeded, sorry [save size=500000] (LuaLaTeX, MikTeX)

I'm getting the following error message compiling my PhD-file (used: LuaLaTeX, MikTeX 2.9):

! TeX capacity exceeded, sorry [save size=500000].
\relax
l.90    \include{M02Part02}

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

Here is how much of LuaTeX's memory you used:

!  ==> Fatal error occurred, no output PDF file produced!

It's quite impossible (and maybe not even necessary) to give you a MWE, because I'm compiling a dozen of files by the include command. The error occurs since I'm using the reledparpackage to create a translation (latin on the left, german on the right) including some index commands and footnotes. I wonder why TeX is 'already' overloaded, because I just wanted to have two or three pages as an output for testing. But, as I read in some other posts, the size of the document as a whole does not cause an error normally. Often, the solution is only: "Use LuaLaTeX!", what I'm already doing!

So... Neither this Problems by enlarging tex memory nor this Compiler error "save size exceeded" nor even this TeX capacity exceeded despite system call LuaLaTeX did work for me. Increasing the memory or the save size didn't have any consequences. I already have the shell-escape included in TeXstudio, and until the recent usage of the reledpar package, I didn't have any problems with it.

Update I reduced my files step by step. There was no error with the reledpar package in my opinion, because everything worked fine until I included my (large) bibliography created with biblatex. I suppose that this could overload TeX because I added quite a lot of adaptions of the style. Maybe that there is to find this coding error mentioned in the commentaries.

Update 2 I managed to compile my files in a normal way by putting only the .tex-files in a new folder, open it an compile it.

Update 3 - MWE I created a MWE in order to see if you get the same errors. Yesterday it worked quite properly. But since today morning, the problem is something with the line numbers, I suppose: Everytime, the compiling is working once, producing a PDF in which the lineation isn't correct, but index and bibliography are created correctly (in the log: Please rerun LaTeX). During the second run, I get the "save-size" warning. I hope the MWE works. I didn't reproduce the structure of my document which I'm creating with front-, main- and backmatter, but I included all the options which I consider important for the problem (and its solution, maybe??). I excluded biblatex which is definitely not causing the error, for better overview.

• "save size exceeded" almost always mean there is a coding error somewhere. Try to make a small example which uses more than a few hundred from the "s" values (499999s). See also tex.stackexchange.com/a/134599/2388 Oct 21, 2020 at 14:50
• My bet is that one (or maybe two (or maybe just M02Part02)) is causing the problem. Try including only a few, and see if you still have the problem. Oct 21, 2020 at 14:52
• @Teepeemm You're right that this file causes the error. If I don't include it, I don't get the error. This is clear, because only in this file, the environment pages of the reledpar package is used. Oct 21, 2020 at 15:00
• @UlrikeFischer Sorry for this question, but where can I find these values? If I find them, I will create a MWE. Oct 21, 2020 at 15:00
• Ok I'll try to create a MWE (probably until tomorrow) which shows the error for you. Oct 21, 2020 at 15:25
