MP2 NMR Error



Dear CCLers,
 I have performed the calculation on 13C NMR chemical shift for
 some compounds using Gaussian 98. But I have encountered the
 error. Embarrassingly I can't calculate the chemical shift
 of reference, TMS.
 The output says:
  Estimated scratch disk usage=    65012376 words.
  Actual    scratch disk usage=    64828629 words.
  (rs|ai) integrals will be sorted in core.

 The following is the input.
 %chk=TMSna

 13C NMR Ref.
 0 1
 I don't know why the job is terminated abnormally, but it seems that this error
 is not due to the system resouces. What means iStart.ne.1?
 Would you please give me a tip of advice?
 sincerely yours,
 Nursekim
