May be you can attach the solve.out file ( Solution > right mouse click> Open solver files directory). How big is the model (number of nodes)? How many modes are you extracting/expanding? Are you expanding all the results ( Analysis settings > Output controls)? It is possible time is being spent on combining the multiple rst files from distributed solver. 4 days is very unusual but perhaps you can reduce what is getting written to the results file.
