this is mostly useless, since it contains a non-portable binary
restart file. please run it through restart2data and provide the
resulted data file.
also, before doing anything else, please upgrade to the latest version
(or at least the latest "stable" version) of LAMMPS. i faintly
remember that there was at some point a bug with restarting an NPT run
that was fixed, but since we don't have specific commit messages, i
cannot easily confirm this or when exactly this happened.
