Is this in your starting structure? Once you get a NaN, everything
beyond that is toast. The usual problem is that you have two atoms on
top of each other, although that doesn't really explain what you are

Try some different method, e.g. solvating CCl4 in CCl4 using the
solvateBox command. Run a few steps of minimization with ntpr=1; use
the checkoverlap command in ptraj to look for bad contacts.
