this is a symptom, not the problem itself. look carefully at the energies,
temperature and so on over time- are they stable?
did you use any non-standard force field parameters? is the temperature
high? is there anything else that might cause instability? was it carefully
equilibrated?
you will have to look into the cause of the problem by analyzing the output.
