I would not know how to make a minimal example that will consistently give the error. I had hoped that this text in the error message: ?Attempt to double-free dir node 54467, ignored? would contain some information as to what might be wrong, but apparently it does not.

Might that mean something like ?too many open files?? Did you try to change you OS?s settings? See http://wiki.contextgarden.net/LilyPond#Too_many_open_files

Or maybe too many files in a working directory (that containing your files or a temp dir of ConTeXt)?

Thanks, Hraban, for your advice. I?ve no idea whether or not the error is connected with ?too many open files?.

It is not. ?dir node? means ?direction node? in this context. Nodes are LuaTeX internal data structure objects. Various bits of ConTeXt manipulate these objects, and sometimes the reference counting goes off and one whose memory has already been given back to the operating system is asked to release its memory again.

The message is harmless, but it points to a small lua programming error somewhere in the source (either by the author or by ConTeXt).

Thanks, Taco. I will stop worrying about looming disasters. Best regards, Robert
