Error in RI-EA-CC2 calculation

Questions
#1

I am running a RI-EA-CC2 but qchem throws an error when calculating the transition energies. Here is the input file:

$basis
aug-cc-pVTZ+3s3p3d
$end

$aux_basis
aug-cc-pVTZ-RIFIT
$end

$rem
MEM_STATIC = 1000
MEM_TOTAL = 64000
BASIS = GEN
AUX_BASIS = GEN
SCF_GUESS_ALWAYS = TRUE
SCF_ALGORITHM = DIIS
MAX_SCF_CYCLES = 100
IQMOL_FCHK = FALSE
JOB_TYPE = SP
METHOD = CC2
EA_STATES = [6,6,6,6]
SCF_CONVERGENCE = 8
POINT_GROUP_SYMMETRY = TRUE
SYM_TOL = 5
EOM_SINGLE_PREC = 1
CC_SINGLE_PREC = 1
$end

Then, when qchem gets to the transition energies it prints:

 CC2  CPU 10994.83 s  wall 3157.90 s
        Solving for EOMEA-CC2/MP2 A1 transitions.

Running a single precision version
      RI-EOMEA-CC2/MP2 right amplitudes will be solved using Davidson.
        Amplitudes will be solved using standard  algorithm.
     Hard-coded thresholds:
     LinDepThresh=1.00e-15  NormThresh=1.00e-06  ReorthogonThresh=1.00e-02

      Roots     MaxVec    MaxIter   Precond   Conv      Shift
      6         120       60        1         1.00e-05  0.00e+00
