CCL:G: A problem in calculation of single point with MP2



 Dear All
 I meet a problem when I calculate single point of TS with MP2 method. I have tried guess=harris,huckel,indo,core...  the errors are the same just as follow:
 "Inaccurate quadrature in CalDSu.
 Error termination via Lnk1e in /home/chem/lbmce/g03/l801.exe"
 
However, the two reactants end normally. I really feel confused.
Hope anyone can help me. Thanks very much.
 
the head of the file is : #p mp2/gen scf=tight guess=..(or no guess)
and  the tail of the file: 
1 2 3 4 5 6 7
 6-311++g(2df,2p)
****
8 9 10 11 .....
6-311+g(d.p)
****
 
sincerely vera
