Dear Julie,
Please send some more information that will help deciding what to do.
Your system has expanded in at least one direction beyond the limits set
inside sander as worst case expansion. This does not necessarily mean that
there is anything wrong, but there is probably a problem with your system.

The data that would help is:
Is it a non-periodic simulation?
What is the nature of the simulation: Are you trying to unfold a
macromolecule? Is it unfolding?
Is there unrestrained water in a nonperiodic system?
Do you have enough output to show what is happening to the volume of the
simulation if it is periodic?
