I occasianlly run into Segmentation fault in my simulations but recently
they become more often. I use NAMD2.9 which I downloaded from NAMD site as

It manifests on two of my machines so far, hence I don't expect any
troubles with hardware. Both machines are running Debian wheezy, but with
different GPU card. I have tried several versions of nvidia drivers.

The simulation usually runs for 10 to 25 hours before it crashes.

Are there any actions I should take in order to debug the segfault?
