Q-Chem fatal error

Dear Support.

I was running an EDA calculation with this setup and this is the first time that this happens to me.

$rem
jobtype eda
eda2 1
method B3LYP
dft_d d3_bj
basis def2-tzvp
max_scf_cycles 350
scf_print_frgm = true
symmetry false
sym_ignore true
DISP_FREE_X HF
DISP_FREE_C LYP
MEM_STATIC 2000
SCF_GUESS FRAGMO
FRGM_LPCORR RS_EXACT_SCF
FRGM_METHOD STOLL
EDA_CLS_DISP TRUE
UNRESTRICTED TRUE
SCF_CONVERGENCE 6
SCF_ALGORITHM DIIS

$end

“Q-Chem fatal error occurred in module libalmo/libalmo/scfmi/subrot_rss.C, line 227”

i do not know what to do next

Regards
SGJ

can you please attach your $molecule, to give us a complete input file that exhibits the error?

What version of Q-Chem are you using?

With the latest version (pre-release copy of 6.0), this job runs to completion in 9.6 h on 40 cores. This is reminiscent of the discussion here,

and therefore may have been fixed in the 5.4 release (although I am not an expert on this particular part of the code).

that could be the case, i am using the 5.2 version of Q-chem, thanks for your time :slight_smile:
