[AMBER] Chains missing during the simulation

Dear all,

I am trying to simulate a protein with 6 chains. Everything goes fine up to
1 ns. From approximately 1.5 ns onwards, 3 chains are missing from the
coordinates.

Could anybody explain the possible reasons behind this?

Here is the input file:
###
NPT_MD Simulation of protein
 &cntrl
    imin = 0,
    irest = 1,
    ntx = 5,
    nstlim = 500000,
    dt = 0.002,
    nscm = 1000,

    ntc = 2,
    ntf = 2,
    ntb = 2,
    ntp = 1,
    taup = 1.0,
    cut = 10.0,
    ntpr = 1000, ntwx = 500, ntwr=1000,
    ntt = 1,
    tautp = 5.0,
    temp0 = 300.0,
    iwrap = 1,
    ioutfm = 1,
 /

regards,
harsh
