We need more information here in order to work out what is going on. Can you
post your input file please so we can see what combination of settings you
have. Also, what version of Amber are you using? Are you using Sander or
pmemd?

Also, is your system box orthogonal? I.e are all angles 90 degrees as in a
rectangular box? Or are you trying to use a truncated octahedral box where
the angles are not all 90 degrees?

All the best
Ross
