Dear all,

I am trying to run minimization on some proteins. For few of the proteins
I get the following error:

 Exceeding lastist in get_istack
   lastist = 4000000
   top_stk= 3667872
   isize = 565248
   request= 4233120
  Increase lastist in the &cntrl namelist

I run the following minimization script:

  #1000 cycles of minimization constant dielectric constant
  maxcyc=1000,ncyc=50, imin=1,cut=9.0,

Can you tell me what the problem is.
