I am running a DFT raman calculation and got the following errors. I have included the input file below also.

You are trying to get the frequencies on a geometry that is not a minimum, since you supplied the actlist line.
My suggestion would be to switch to numerical frequencies. Numerical frequencies do take into account the actlist line, while analytical frequencies do not.

Thanks Edo. The geometry is a minimal and the calculated frequency has a neg of ca. 10 wave numbers. The active list is commented out but when I copy and pate the comment sign # ended up as numbers on the forum page.

Does this mean that the CPHF failure occurs during task raman, while task frequencies works?

Yes that is right. CPHF for frequency calculation works and it failed for the raman calculation.
