Please check geometry in SpaceClaim. 
Select geometry in structure tree --> Use right click --> Select Check Geometry. (Or Tools - Fault Detection in DM)
The geometry should be error free to proceed. 
If geometry has any errors, please modify/recreate geometry at those places. 

The import time also depends on what file format you are using. Please use SpaceClaim file to import in Fluent Meshing. 

Please go through help manual for more details
