Subject: SOLVED: too many open files
Date: Thu, 15 Aug 2013 21:48:09 +0600	[thread overview]
Message-ID: <EAC7C721-8AB4-4B52-A3B8-86A4087A3289@fiee.net> (raw)

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:

!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...

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.)


Greetlings, Hraban
