[NTG-context] infinite loop with a huge document

Dear list, I’m afraid I have a huge document (combination of more than 80 individual documents) that triggers an infinite loop. All of them are Markdown sources that I convert to HTML4 and compile with ConTeXt latest. Individual documents compile fine, in about 3 or 4 runs. The single document goes always for the maximum number of runs. There were 9 runs, which is the default number. I set "--runs=30" and compilation ran through 30 cycles. So I use now "--runs=5". The document is huge and its compilation process is complex. Is there any way in which I can investigate what triggers the compilation in endless cycles for this document? Many thanks for your help, Pablo -- http://www.ousia.tk
