Hello thanks for the blazing fast answer! From what I understand, if I provide a graphView per thread the problem should not occur, is that correct? Regards, F. Le 10 oct. 2016 19:32, "Tiago de Paula Peixoto" <tiago@skewed.de> a écrit :

Hello,
I suspect the copy_property function not to be thread safe. Remember that the issue I observe occurs when I re-use the predecessor map returned by shortest_distance. The copy_property is then called from topology/__init__.py:1441 and the parameter full is None.
I didn't realize all the workers shared a reference to the same graph.
Indeed this can be improved. To be honest, thread safety from the python side is something that I often do not pay attention to, since it is almost never worth it. But please open an issue in the website to make copy_property() thread safe, and I will get around to it.
Best, Tiago
