Dear AMBER users,

I am trying to continue a md simulation of a nucleic
acid in explicit solvent. When the simulation is
started in a new machine the program exits with an
error message after 250 steps of calculation. When the
calculation is started again, the program exits with
the same error message,without doing a signle step of
The error message is,
