Hi again,
in my current songbook project I use t-filter with LilyPond as shown in http://wiki.contextgarden.net/LilyPond with latest beta MkIV on OSX.
Every line (system) of notes is included as its own PDF to leave the page breaking to ConTeXt. But since I have some hundred songs with each a few lines, it sums up...
I guess ConTeXt keeps every externalfigure open, since I get this error:
pages > flushing realpage 70, userpage 70

It works with songbook excerpts (some 30 songs). I don't understand if the error is really from LilyPond or from LuaTeX (I guess the former), and how I would be able to increase the number of possible files (in bash on OSX 10.8.4). So probably it's more a general Unix question than a ConTeXt one, but anyway...
ANALYSIS:
$ ulimit -n
256
$ sysctl kern.maxfiles
kern.maxfiles: 12288
$ sysctl kern.maxfilesperproc
kern.maxfilesperproc: 10240
SOLUTION:
$ ulimit -S -n 2048
(Properly describing a problem often helps to solve it. I send this for the records, in case someone runs into the same.)

afaik the limit for simultaneous open pdf files in luatex is 2K so it's
indeed your operating system

OT: The thriddata.parselilypondfile(..) function is convoluted. Instead of
for ts in io.lines(scname) do
syco = ts*1
end
you should use
syco = tonumber(io.loaddata(scname)) or 0

Thank you, I changed it.

Hi,
I found an old thread while fighting with the problem of
luatex I/O Error: Couldn't open file 'foo.pdf': Too many open files.

I don't understand if the error is really from LilyPond or from LuaTeX (I guess the former), and how I would be able to increase the number of possible files (in bash on OSX 10.8.4).

Running "ulimit -S -n 2048" in fact solved the problem for me, but I
wonder if there is any better solution. (I might even have more than
256 files open in my text editor and that one doesn't complain.)
Is it possible to politely ask LuaTeX to close the files after reading them?
(It's fine if that's impossible, I can still use Hraban's workaround.)
Thank you,
Mojca
