I did an equilibration run using amber8, with the following input file:

   IBELLY=0, nstlim=100000, dt=0.001,
   irest=1, ntx=7,
   cut=9.0, nsnb=10, ntwx=1000, ntpr=1000,
   scnb=2.0, scee=1.2,
   ntt=1, temp0=300.0, tempi=300.0,
   ntb=2, ntf=2, ntc=2, ntp=1,
   ntcm=1, nscm=500,
    use_pme=1, vdwmeth=0, eedmeth=1, ischrgd=0,
    nbflag=1, skinnb=1.0,

But everytime the job terminates abnormally with the following error msg:

lib-4324 : UNRECOVERABLE library error
Encountered during a namelist READ from unit 5
Fortran unit 5 is connected to a sequential formatted text file: "mdin.1"
IOT Trap
MPI: MPI_COMM_WORLD rank 0 has terminated without calling MPI_Finalize()
MPI: aborting job
MPI: Received signal 6

Can someone tell me what I am doing wrong/missing here ?
