this is line 151 of file vcsmd.f90:
      READ( 4, * ) rati, ratd, rat2d, rat2di, tauold
Unit 4 should be "siderite.opt.md" (I am assuming that you are
running the sederite_espresso job you posted a few days ago).
Look in that file - it is formatted and quite small - for anthing
looking suspicious: NaN, missing spaces between numbers, etc.

once upon a time, on a Cray machine, read(5,*) didn't accept the
format N*value that write(6,*) used when N consecuting variables
had the same value. Really!
