Hi

I am equilibrating the waters of a neutral system,
while holding the solute fixed with a force of 500,
I am able to run dynamics without PME, but as
soon as I try PME, I immediately get the following error message:

APPROXIMATING switch and d/dx switch using CUBIC SPLINE INTERPOLATION
 using 5000.0 points per unit in tabled values
 TESTING RELATIVE ERROR over r ranging from 0.0 to cutoff
| CHECK switch(x): max rel err = 0.1050E-11 at 2.448780
| CHECK d/dx switch(x): max rel err = 0.9064E-11 at 2.784040
 ---------------------------------------------------
     Total number of mask terms = 6876
     Total number of mask terms = 13752
| Total Ewald setup time = 0.23723257

------------------------------------------------------------------------------

 EWALD BOMB in subroutine ew_recip/grid_weights
 nmine exceeds num_ks
 System must be very inhomogeneous. Cannot continue.
