We're going to need more info. Since RAMD is predominately a Tcl-script
based implementation at present, your particular input, any altered
scripts, and underlying parallel infrastructure (charm++ version, mpi vs
non-mpi, network, etc) could be involved as a potential problem.

More detail on the output, or a copy of the last 20 lines of the log file
might begin to help.
