Dear All
I am doing linear response CCSD calculation and i want to calculate dynamical polarizabilities at imaginary frequencies for set of molecules for some molecules it works fine but for some it is not converging at lower frequencies. 
Below is the input followed by "trimmed error output" for which it is not working
Please let me know possible solution for this problem or if there is any mistake in the input.
