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:

 Error: Couldn't open file 
 Too many open files.

!LuaTeX error: xpdf: reading PDF image failed
 ==> Fatal error occurred, no output PDF file produced!

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...

$ ulimit -n
$ sysctl kern.maxfiles
kern.maxfiles: 12288
$ sysctl kern.maxfilesperproc
kern.maxfilesperproc: 10240

$ 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.)
