This is generally a symptom of deeper errors. You need to make sure that
your energies are stable, that you have equilibrated to 300K with constnat
volume, and that your value of taup is not too small.

If these don't help, please provide more information, including how big
your system is, what version of amber you are using, and as many details
as you can about what is going on.
