RecursionError: maximum recursion depth exceeded while calling a Python object

[villanella]

I have one group of documents (requirements, use cases, tests) for each issue in the large project. When my Doorstop-project became bigger (40+ documents), I begin getting error on publishing project: "RecursionError: maximum recursion depth exceeded while calling a Python object", but html pages are successfully created. Is the error is caused by size of project? What number of docs are recommended?

Doorstop v3.0b4

I will respond briefly with my experience on this matter. I had this error when there was a cyclic requirement trace (parent to child, and child to parent). I had a similar experience with document publishing-- I believe everything was published with the exception of the index file which hosted RTM matrix. This may not be your issue, but I would hate not to share if it was.

Thank you, I removed cyclic links and the error has disappeared.
