Dear all,

I'm trying to do an CIS optimization on a closed shell molecule using 
G03 B.05 and the calc stops with the following error while calculating 
the second derivatives:

Doing CIS second derivatives.
This link is doing    39 degrees of freedom
Form MO integral derivatives with frozen-active canonical formalism.
CisSec: MDV=       6291358
Frozen orbitals handled with amplitudes over full window.
Frozen-core window:  NFC=  28 NFV=   0.
The selected state is a singlet
Computing gradients using direct method.
Cannot handle 2e integral symmetry, ISym2E=1.
CISAX:  IP=  1 NPass=   1 NMax=  39.

Does anybody know why this error occurs and how it can be 
resolved?

Many thanks in advance,
