Why can my XFEM method in Abaqus not predict crack grows?

When I use the XFEM method in Abaqus to predict fracture of my materials, Abaqus gives good results about crack initiate and maximum load, but it can't predict crack grows. In Abaqus, after...

Why is this error in abaqus XFEM method: too many attempts for this increment?

I simulate crack grows for a specimen in abaqus and use XFEM method. When my crack initiates and grows a bit and before full break the specimen I faced this error: too many attempt for this increment.
