[AMBER] Resolving overlapping atoms.

Hi List.
After adding water by addtobox to a pDB and ruining minimization I still
have some overlapping water hydrogen. For now I came up with a crude
solution and remove these 2-4 waters. But is there any way I can force
minimization to solve it?
here is my minimization parameters :
"""
simple generalized Born minimization script
 &cntrl
   imin=1, ! initiate minimization
   ntb=1, ! use NVT ensemble
   maxcyc=100000,
   ncyc = 3000, !was 1000
   ntpr =10,
   cut=12.0, ! cutoff 12 Ang
   ntr=1, ! weak positional restrains
   iwrap=1
/
Keep protein fixed with weak restraints
10.0
RES 1 {0}
END
END

The output of minimization repeatedly tells
 .... RESTARTED DUE TO LINMIN FAILURE ..

Thank you.
Petro
