Dear Priyabrata,"Segmetation violation" and other errors Gaussian prints in terminal are generally useless for tracking back the error. NtrErr usually means that the program tries to read the checkpoint (or RWF?) but cannot, for example, there was no disk space and the information was not written in some previous steps. Is there also some message in the output like "Erroneous write" or "Operation on file out of range", or "No file to extend for", or "Transformation cannot fit into", or "File extend in NtrEx1 failed"? You can post last 10 lines of the file in this case, it might be helpful. Do this also if Ypu encounter other errors when there is no archive section at the end of the file; otherwise You need to compare with some successful job of the same type and post the differences in messages (not coordinates or like so, of course).
