Hello, duarouter is using Dijkstras algorithm (or A* if you set the appropriate option). duaIterate.py performs gawrons algorithm by calling duarouter and sumo iteratively. The number of iterations needed depends on the scenario. Also, we have experienced problems with the convergence of gawrons algorithm in some networks. However, deadlocks in a scenario can have many causes. see http://sumo-sim.org/wiki/FAQ#The_simulation_has_lots_of_jams.2Fdeadlocks._What_can_I_do.3F
