Hi all,
     I am doing an NVE run of my protein with PBC. The version of namd used is 2.5. It was running on 8 processors with a parallel version. My run crashed after 3 million steps giving segmentation fault error listed below. I read a few previous mails from archive but could not make out how to resolve this? NO such problems arise with spherical boundary runs, why so?
I see no bad energy (in the sense too high) vales or any thing else in log file. I am not sure whats going on? Can someone from development team help me out:
