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...

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