Mehul is on a distinguished road

I am facing a strange problem in ICEM CFD. When I try to start the mesh by Compute mesh for one of complex geometry, ICEM initially goes fine. After some time, it crahses without giving any mesh ( It does not create any *.uns file). I obserevd that, when it tries to split edges at surfaces or somtimes at trilateral round at curve during computing mesh, It crahes. I appreciate, if any body can share their experience, if they would have faced same problem. As far as my my geometry is considered, it is almost without any holes. Is it due to huge no of curves or any deformed surfaces. For the same geometry I was able to perform mesh sometime back, but now I have added few parts, and not able to do the mesh. I would request any experts to give their opinion. One more thing, I would like to add is, when I increase scale factor too much, then I get the mesh, but that is with many holes, which is not acceptable.
