Dear All,
  
 I tried to do the following calulation:
  
 CIS(full)/cc-pVTZ Xanthene geometry optimization and frequencies
 calculation of 1st excited state.
  
 in Gaussian98 and received the following error message:
  
 Inverted reduced A of dimension 886 with in-core refinement.
Max Tx.T =      0.000249024916 for Degree =     3
Tx not orthogonal to T.
Error termination via Lnk1e in

 What is wrong here? Why is this appearing
Any help will be very appreciated.  Thank you in advance!!
