Hi again,

in my current songbook project I use t-filter with LilyPond as shown in

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:

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.)


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?


maybe object=no helps

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.)

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