Freq calculation in QChem not ending

Questions
#1

Hi, I am trying to calculate the vibrational frequencies of the excited state of a molecule following geometry optimisation and it has been running for more than a week without any frequency output so far in the output file. I see a warning
!!.
!!Warning*.
!!Desired Analytical derivatives not available.
!!Finite difference job might take a long time.
!!.
!!********************************************.
at the beginning of the output file and do not understand what’s wrong.
Here’s my input file.

$molecule

$end

$rem
JOBTYPE freq
METHOD wb97xD
BASIS 6-311G*
CIS_STATE_DERIV 1
CIS_N_ROOTS 5
CIS_SINGLETS true !False for triplet optimization
CIS_TRIPLETS false !True for triplet optimization
MEM_TOTAL 4000
MEM_STATIC 100
MAX_SCF_CYCLES 200
MAX_CIS_CYCLES 200
$end

Please help!

Analytic Hessians are not available so the calculation is using finite-difference of analytic gradients. That is what the message means. The cost will be 6*NAtoms gradients, you could therefore estimate the frequency cost by running a single gradient calculation using JOBTYPE=FORCE.
