mesh neighbor list overflow

hello,

I am trying to perform a simple simulation where I have an auger rotating inside a specified volume filled with powder, but after couple of hours of simulations, I am getting the following error:

ERROR on proc 0: mesh neighbor list overflow, boost neigh_modify one and/or page (../fix_contact_history_mesh.cpp:344)

so what is exactly the cause of this error? And how can I solve it ? Would boosting neigh_modify change the results of my simulation by in terms of particles' properties?

please find the input script I am using:
