saltcon should always be set to 0.1, since that's the value that was used
for calculating the reference energies.

Nothing sticks out as obviously wrong with this input file that would
cause it to crash (although I made a comment about saltcon above). Look
for an error message either printed to stderr (the screen if you are
running interactively, or a file if running with some kind of scheduling
manager like PBS) or the mdout file.
You didn't give nearly enough information to let us determine what may have
happened.
Good luck,
