It's case dependent, but 5e-6 continuity residuum is low. What makes you think that the case is not converging?
There are different methods to judge convergence, as: residuals, mass imbalance, or plotting values. Did you try to plot some value every iteration, like a node value of pressure in some location, or the average pressure on some wall? If such value does not change in the subsequent iterations (remains stable) it may indicate that the solution is convergent.
