CCL:G: termination failure when calculating the single point energy

 Dear Dong  Fang!
 I have achieved the convergence (please see below the right answer)   in SCF 1
 very fast.
 The correct route seection is
 #p rob3lyp/6-311++g(2df,2p) sp scf=(vshift=100,tight,maxcycle=512)
 the archive section is
