[AMBER] problem with gas-phase MD simulation in Amber8.

hello everyone,


 I was trying to run simulation for a small arrangement of two molecules (26 atoms) in
 gas phase. I generated the prmtop and inpcrd with leap. If I soak it in a
 ACN , solvatebox, the simulation runs perfectly well. However I can't run it with
 the molecule in gas phase.
 my input file looks that:



 &cntrl
   ntx = 1,imin = 0,
   nstlim = 50000, dt = 0.001,
   scee =1.2,
   tautp = 1.0, cut = 9.0,
   ntc = 2, ntf = 2 ntb = 1, igb = 0,
   ntwe = 1000, ntwx = 100, ntwprt = 0, ntpr = 1000,
   scnb = 2.0,
   temp0=298, nmropt=1,
   ntt = 1, ntp = 0, taup = 0.5,
   vlimit=10.0
 &end
 &wt type='END' &end

DISANG=wiezy_3.in
LISTOUT=POUT
 
 
  when I run this, job is killed.
 
 when I done my arrangement in leap I added setbox ({30. 30. 30.}).
 
 I do all things in Amber8.



 Does anyone know what is wrong and how to run a gas-phase simulation?

Thanks in advance.
martha.
