RI-MP2/def2-tzvppd convergence issue for calculations with iodide

Hello,

Unfortunately, although my calculations are getting to further steps, I still have a problem of convergence. Attached are two outputs from the same calculations.
The only difference is the range of distances I am using :

  • dimer.dat : 2.0 to 3.0 angstrom; ends successfully.
  • dimer2.dat : 3.0 to 5.0 angstrom; does not converge.
    This brings me to a question, is it possible to continue the calculation when we fail to get to convergence ?

Thank you.
