Dear Daniel,
Have you looked into namd’s use of restart files? With appropriate configuration they regularly produce files that can be used for clean restarts.
Why would you have an ‘exit’ file and not just send a termination signal to the namd process?
Best,
Peter

A script, who build the NAMD-scripts and start them, could see this file and stops too (that’s why don’t remove it with the restart writing).
