HI Hans,
I have tested this project down to every little snippett and I never get this error with the message as described, unless the whole project, a book of about 450 pages with around 400 graphics, is processed with interaction, and even then it does not always occur. It may or may not happen.
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.
Anyway, thanks for your attention.
 
Best regards,
Robert

well, it can be an issue in the engine as well as in context and it's 
hard to guess where and why it happens, so we need to wait till we have 
a predictable and repeatable case

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, Taco. 
I will stop worrying about looming disasters.

Thanks, Hraban, for your advice.
I’ve no idea whether or not the error is connected with “too many open files”. The Project needs some 40 files but its working directory contains some 120 files  (most of them only for testing purposes). Moreover, I usually only have the “project-file" open during processing (but I don’t know if that is important here).
Surprisingly, as I wrote in my first post on this subject, the error up till now only occurs when I use interaction, and it usually does not occur anymore, at least on the same day, after I processed it once without interaction. But the next day, after sleep (of the Mac), the error may occur again.

I did not change the settings but I will in case the problem gets worse.

Best regards,
Robert

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).

Best wishes,
Taco

Erratic error message

[Robert Blackstone]

[-- Attachment #1.1: Type: text/plain, Size: 3850 bytes --]


Hi all,
When typesetting my project with interaction, sometimes the processing stops after a few runs with an error message that points at an empty line in one of the chapters that normally gives no trouble. 

For interaction this setup is used:
\setupinteraction[state=start,focus=standard,style=,color=blue,contrastcolor=]
\placebookmarks[prechapter,chapter,section][prechapter,chapter,section][number=no]

When I comment out the first of these two lines, in other words, without interaction, the project is processed without any problem.
Sometimes, unfortunately not always, when I immediately repeat the processing with interaction, all goes well. 

So what is my problem? Not understanding what might be wrong, and not being able to correct things gives me a feeling of insecurity, trusting Murphy’s law to make sure that processing will fail when my deadline is approaching fast.

I use mkiv on Mac OSX 10.9.4. All my standalone versions from january up to today give the same behaviour.

I mostly get the following  error message:  (occasionally something different happens: the processing gets into some endless loop and I have to abort it)
